content: Learning its capabilities ..... somewhat more than the SVA1000X models......GPS and MAP tile files are new to me and used to record coordinates of remote transmission/repeater stations.VNA sweep of SWR and Log Mag from a 200mm 2.4 GHz WiFi SMA antenna displaying further resonant frequencies.Seems GPS has no problem finding satellites even when inside under a tin roof.Outside I've had 17 show up which of course much improves altitude accuracy.

content: I received mine today. The firmware version is 1.1.2.1.6R0. It seems that the firmware and the user manual still require some refinement.

content: Quote from: lty1993 on September 04, 2023, 08:03:15 amNice.Had mine a couple weeks and it arrived with the now online FW, V1.1.2.1.5R0 for which I now have a beta version a little later than yours.However the Option page Trial times weren't displayed correctly (no 120hrs Trial mode) and I got a special file from HQ to remedy it.Yes the manual is under further development and I have a section on MAP that is not added to the public manual yet.What do you need help with ?

content: I can confirm that my unit was shipped without any trial license installed. It only has the F1 and CAT permanent licenses installed by default, as it is the base model.I can see on siglentna.com that GPS and GPSM are out of stock. It is possible that they are not finished functions and are not available for purchase by the public.I don't currently require assistance with anything. Everything is going well so far. I simply want to share my experience.

content: Quote from: lty1993 on September 04, 2023, 01:56:40 pmYes spotted that too however it's outdated as I purchased GPS and GPSM.The GPSM option has been renamed as MAP in the instrument although still is listed as GPSM in pricelists and on websites to better align with UI menus.https://int.siglent.com/article/detail-952.htmlWith the beta FW and license patch the screenshot below is what the Options page should look like with Trial options displayed and the MAP option is below the bottom of the page.

content: Quote from: tautech on September 04, 2023, 11:33:51 pmLOL, if you're going to patch a license, why not make it permanent? Actually, you can extract the license code from the running program while adding an incorrect license to it.

content: Getting to know this more to see what the trace colors are for the 6 traces it can do.3 GHz @ 0dB from coughSSG3021X via RG214 with 10 Hz RBW and missing a couple steps to 300kHz RBW.All traces Peak Hold however with the long sweep times for low RBW settings I haven't allowed for multiple sweeps to display less noise.

content: SA newbie dropping in to this thread… I’m (somewhat) in the market for a spectrum analyser, portability is actually maybe a nice bonus as I have to travel a fair bit so these SHA800A units came up…However my needs are mostly basic & learning on the radio/antenna front. I’m more interested in EMC/EMI pre-compliance related features for an actual paying project.I noticed that Siglent NA lists a SHA850-EMI unlock option for these units but this is completely unmentioned in the data sheet. Does anyone know more? Is this a new addition to the software? Does it contain the same features as the other less-portable units?Any other “gotchas” to think about comparing these units to something more desktop - say the SSA3000X Plus?

content: Quote from: seajayshore on September 25, 2024, 09:17:02 pmGood catch.Older pricelists don't show the EMI option yet the latest does.Will reportQuoteMore.Additional traces.GPS & Maps < which need be PC downloaded, created and installed.QuoteThe Source option is TG which with SSA/SVA models is free.UI is very different to SSA/SVA models yet quite capable.I have the 7.5 GHz model so if there's more you need know I can demonstrate when time allows.

content: Thanks for the reply! It really does look like quite a neat unit. I have a UK distributor who will rent them so might trail first...I also noticed the RTSA variant in this thread. Looks a fantastic little unit - higher bandwidth real-time mode than even the SSA5000A if my reading of Siglent China webiste is to be believed!Any idea when the 860A model is coming to the west...?

content: Hello, I have been looking at this amazing unit, as far as scan points on its sweep, the manual lists 201-- 10001 points. Is it continuously variable? or a default depending on the span? and what is the default setting.thanks.
