content: So, I was capturing some IR signals with CH1. Then I decided to do a math operation (-) between a signal that I saved as REF_A and the one that I just captured at CH1. Once I tried to select my sources, the scope only offered CH1 and CH2 (grayed out) but not my saved reference. I checked the manual, and it specifically says that I should be able to select my reference as a source. So, what am I missing?

I know Chrome doesn't like to connect to HTTP sites and defaults to HTTPS. I haven't verified if HTTPS is natively supported on Siglents firmware so using IE or another browser may allow you to connect to older HTTP port 80 sites easier.

Siglent SDG1000x and .01uf capacitor - Page 1

content: I'm getting in to cb radio repair and recently purchased a SDG1000x generator. My radio repair manuals say to put a .01uf capacitor in series with a signal generator test lead. It is an old manual. Is a .01 cap necessary with my Siglent SDG1000x, or does the sdg1000x internal overvoltage protection do the same thing? Is the purpose of a .01uf cap to block DC from the radio reaching the signal generator?

timestamp: January 21, 2022, 10:42:57 pm
content: It is rather to prevent DC from outer circuit to radio. There mustn't be direct DC coupling. AC coupling is allowed only.So, you still have to use 0.01 uF cap.

author: TimFox
author_rank: Super Contributor
timestamp: January 21, 2022, 10:56:35 pm
content: Normally, the output from the signal generator should look like 50 ohms to ground at DC, which may not be appropriate for the circuit that you are driving. Hence the need for a "DC blocking" capacitor. 10 nF in a 50 ohm circuit gives a corner frequency of < 1 MHz, which will pass everything you need at RF.

There is a short-circuit protection, but not sure at what resistance its triggered, and how safe it is to trigger it.I'm also wondering about how much it is safe to sink, I'm thinking on some passive filters like RC ones, I want to stay safe and avoid breaking anything...Thanks in advance...

An indication of your budget would also help immensely as there is no point people recommending equipment which is out of your reach.Wavecom Instruments currently have the SDS 1052DL+ listed for $351 and the SDS 1102DL+ for $383 both including GST so it's only $32 extra for the 100 MHz version. Wavecom also sell on Ebay where they are listing the SDS 1052DL+ for $319 and the SDS 1102DL+ for $368 both with free shipping so their pricing is all over the place.

content: I've never bought SDS1052DL into NZ mainly due to their minuscule memory depth for a DSO.Instead to get the best from a DSO's abilities you are much better off with a min of 1 Mpts memory depth and preferably more.As this is to be your first scope in that you'll learn to use DSO features and in time you'll come to understand the limitations of a DSO with very little memory.With all this ^ in mind the least capable Siglents I sell are SDS1102CML and more lately the Plus version that now has the higher res display and a LAN connection.Good luck with your hunt.

content: Not sure I fully understand what you are after. You want to acquire a sequence which captures every edge (rising and falling) of CH2 with high time resolution, and you want to also see the falling edge of CH1 -- is that it?If this is what you want to do, I see several possible ways:(a) Trigger on CH2, set the trigger threshold so high that it also gets triggered by the small dip which comes at the time where CH1 falls, capture a sequence.(b) Trigger on CH1 falling edge, set trigger delay and timebase such that you capture all relevant CH2 edges before that. Don't use sequence mode at all, but use zoom to look in detail.(c) Do the two analyses separately. This assumes that the CH1 bevahior is independent of the specific shapes of the CH2 edges, so you can first scrutinize one, then later the other.

Enable full memory depth for the initial acquisition, then you can zoom in a LOT!QuoteYes, but does that falling edge in CH1 get affected by the exactshapeof the CH2 edges? I.e. do you need to see that exact shape in CH2 when you are checking for CH1, or do you just need to see that the CH2 edges are present, or count them, when you scrutinize CH1?

content: Hello All. I have done a cursory search and reading for the Siglent SDS112X scope as I hope to purchase one for home use in the next few days. A quick note that I have used numerous electronic equipment over the years but I am primarily a university teacher and researcher in physics. The intended scope is for some fun projects at home.My main takeaway is that its price per feature is excellent but you get what to pay for especially in terms of firmware.My major question concerns this, as I've noted that most reviews site this as a negative of these lower cost scopes.Siglent came up with an update recently; I thought it was for their 2000's series but some posts mention this applies to the 1102x as well. Is this true?How buggy is this scope? is it something that shows up primarily at its limits? or is it an issue even within normal range; let say analyzing a 100ns squarewave with around 2ns rise time?

There are two buttons looks related to this, Decode and Setup both have its own protocol UART, Channel select etc which one to use?2. While selecting RX TX channels label RX means its scope's RX pin or its should match with uC RX pin? (ie. RX > RX and TX > TX)3. how to use threshold, I'm using uC at 3.3v, scope channels also have voltage levels, I set Channel voltage to 3v and threshold at 2.2v is that ok? i believe threshold is the trigger point or valid logic level point?4. Setup button is located on Trigger channel, does that mean whatever TX/RX i want to use as Start decoding signal must use channel 4?5. when i press Decode button it shows two decoding rows S1 and S2 what is the concept behind this?If someone have experience using UART decode please explain how can i setup. thanks

The manual says this about the Threshold setting:Quote4. See page 118 (numbered page 99).5. Those are the decoded bytes.

Siglent SPD3303X-E sparks between positive and earth terminal - Page 1

timestamp: April 14, 2021, 02:31:49 pm
content: Hello!I picked up my first lab power supply after years of not having anything. It is a Siglent SPD3303X-E.This is a linear power supply with two independent outputs that can be connected in series or parallel. As far as I know, the outputs should be "floating".I turned the power supply off but I still had it plugged in to the wall. I started measuring the spacing between the banana terminals with a caliper. I measured them by the base, where some metal is exposed.When I bridged the positive output of channel 1 with the green earth connector and I saw a spark. It was not big, and it did not spark again while I kept measuring things. If I'd have to guess, I shorted a capacitor.As far as I can see, nothing is broken.I tried measuring the voltage between the earth connector and the positive output terminal of channel one but it's only a few millivolts.So, to the question:Is this normal?The only thing that I can think of is that there is a capacitor between earth and the output terminals (I've seen this in some power supply designs) and when I touched the output connectors with my caliper, I shorted that capacitor.

content: Cap would be my guess too. The Earth terminal is at mains earth potential if the need arises to couple it into your circuits for any reason.Yes the outputs on these PSU's are floating and there is a 500V isolation spec from mains ground.When in series mode several of these PSU's can have their outputs series'ed to supply a max of 500VDC.

content: SPD3303X-E has 100nF capacitors from each channel to mains earth. It is for sure possible to see a little spark if this capacitance gets charged to more then a few volts. Normally it should not charge to high voltages by its own. Something external connected to the output might do it.

content: Welcome to the forum.SDS1000CNL & CML range share nearly the same HW, except the CNL has 40K memory vs 2M for CML.They both have 1 Gsa/s sampling speed.Both are 2 channel models.SDS1000CFL range is quite different, 2 Gsa/s, 4 channels, 24 K memory.http://www.siglentamerica.com/pdxx.aspx?id=58&T=2&tid=1The sampling capability must be shared between channels and for this reason the CFL has double the sampling to maintain 500 Ks/s with all channels active.But if only one channel is used the full sampling speed will apply to that channel.The CML and CNL ranges are the most popular, the additional memory of the CML useful when analysing complex captured waveforms in detail.

content: The "D" ranges are the lowest cost range with only 500 Ksa/s to be shared between both channels.Also only 32 K memory.The "D" may not still be available, it has a 5 inch display vs the more common "DL" 7 inch display of the current models.http://www.siglentamerica.com/pdxx.aspx?id=26&T=2&tid=1But with all Siglent models they also have 400V rated channel inputs for greater protection of the scope when used on HV circuits.

content: I'm trying to use this sigma-delta ADC (MCP3911) for its quick settling time, and I'm a little confused about the input ratings.http://ww1.microchip.com/downloads/en/DeviceDoc/22286A.pdfThe differential inputs are rated +/- 1V and are fed into a PGA before it gets to the modulator. Table 1-1 shows that the Analog Absolute Voltage on CH0+, CH0- can range from -1V to +1V, measured to AGND.So can this ADCactuallymeasure a 2Vp-p signal centered around GND? I'm confused because it's only a single-supply chip, and the block diagram doesn't show any internal voltage inverter for the PGA.Do I supply -1V to REFIN-? Do I need to do the same for REFIN+, or can the ADC use the internal reference instead?Thanks for your help!

I need some practical advice from the people working with PLC modules, in regards to wiring everything up.Do I need pull up/ pull down resistors on their inputs for momentary switches or RC circuits to condition the signal, or do I assume everything is built inside with sufficient latency, to ignore signal spikes, or bouncing switches, and other noise coming from surrounding electronics?If yes, how do people installing PLC make it neat and robust?Cheers

Some models (24, 24R) are oriented toward logic levels (albeit higher voltage than , say, TTL)Why not start with the User Manual around page 5 Section 2.2 (PDF page 12)?

content: For breadboarding circuits, 5 MHz is more than enough.Yes, there are a lot of projects clocking a lot faster but they have their own signal sources. For the kinds of things I might breadboard, analog circuits of some kind, 100 KHz is fast enough. Audio only runs out to around 20 KHz anyway.5V P-P is more than enough. If you were playing with a transistor amplifier with a gain of 10, your collector voltage would be swinging through 50V P-P and that's a lot for a breadboard project. What you really need is a clean sine wave down in the millivolt range. 1V is likely to be more than enough and, if it isn't, well you have 5V.

content: Hi All,I am trying to construct a test rig that will send clock pulses to some boards that have a 4013B flip flop wired as a latch. Rather than directly connect the output of a signal generator to the clock input I thought it would be fun just to add some extra complications and drive the clock pulse from a mosfet instead and drive the gate with my signal generator (Rigol DG822).This is the circuit:For my reference I have an LED also on the source so I can visually see the clock pulses get sent, however, an interesting thing happens.My signal generator is set up sending a PWM of 1hz and duty cycle of 10%:probed at the mosfet source:You will notice the first pulse is when I enable my sign gen output, you can see the rise time is much longer than the other pulses, here is the first pulse on its own:Here is the second and beyond pulse:This long first pulse is causing the 4013bs to go wobbly as its a invalid clock rise time but why does only the first pulse do this?I have connected my sig gen directly to my scope input and every pulse is perfect, so it must be my circuit to blame but I am not sure why.Any help would be appreciated.

And yes, it definitely can damage your unit under test (UUT).Quote from: Mike Fikes on January 09, 2019, 10:57:48 pmNot too sure what you mean here but I will cover all combinations.Test equipment, apart from possibly specialist types, can be turned on and off with no UUT connected to them or with a UUT connected to them.In strict theory test equipment should be turned on and then connected to the UUT, but nobody does this.In a typical set up you may have a UUT connected to three PSUs, a scope, a signal generator and frequency counter say. The monitoring test equipment is not critical. But the PSUs are critical and you would need to check what the UUT requires. There are also situations where a UUT may be stressed if a signal source were connected but the PSUs were not.The switch on negative output of your Rigol DG1022Z, reminds me of the time at work when we started getting a load of UUT failures, until we discovered that the lab PSUs we were using outputted a 70V spike at turn on.

content: Yes, relays are pretty reliable even when powered for a long time, failure is given for a cycle count depending on the current and voltage conditions while commutating rather than on time or duty.If powering them for long periods you might want to use a parallel RC in series with the coil, so when you switch them you get a spike in current able to do the commutation and then go to a lower current to hold. This saves power and makes the coil more tolerant to higher voltages than rated if you are powering it from a bad power source.Note that for the 12V coil the operate voltage is 9V and the release voltage 1.2V, so you need at least 9V to go from one state to the other but only need to warrantee 1.2V to hold the contact in place. If there is a case where you de-energize the coil for a moment and then reenergize it again you need to be sure the cap discharges in between.JS
