content: SOLD Locally.For Sale in Canada to worldwide: Tektronix 2465A Analog 4 channel, 350 MHz OscilloscopeI need to sell some scopes, and it breaks my heart to part with this one, but that's the deal I made when I bought my Lecroy.This is a 4 channel, >350 MHz pure analog scope from near the end of the analog scope era. It has voltage and time/frequency cursors but not the automatic measurements that the 2465B has. This particular model has the digital board with through-hole capacitors (no leaky SMT electrolytics), and the SRAM with separate lithium battery. So far the battery is holding, no calibration problems, and no self test failures. As I understand it, when the battery gets low, a power on self test should detect it and display an error so you can take care of it before losing cal data.I've measured the rise time at 1 ns, and the -3 dB bandwidth at 375 MHz (HP 8657B as a source, into 50 Ohm input). It will still trigger on and display a >600 MHz signal.It has the original Tek transparent (actually slightly rose colored) contrast filter, and I have made two DIY contrast filters, one blue and one green. Neither quite matches Tek blue but they are very effective. See photos. I personally prefer the clear one. I have replaced the graticule/scale illumination lamps with white LEDs. It works and looks great, and should last longer than those grain-sized bulbs. Comes with the quite rare front panel cover and the probe pouch. No carry handle. Two of the feet were missing when I got it (how does that even happen?) but I have effectively replaced them with little foam rubber blocks. There are some scratches in the ID plate above the display. One knob was replaced and doesn't perfectly match the others. Besides those little issues it looks and works great, as you can see in the photos. None of that "powers on but I don't know how to test it" ebay nonsense. This is a working instrument in great condition.It has XY mode and Z input so you can run those interesting audio XY demos ("lissajous music", etc.) you might have seen on Youtube. With the Z input you can also do brightness control or blanking for oscilloscope pong or vector graphics, or build a composite video display like seen on w2aew's avatar.Includes four Tek P6138 350 MHz 10:1 probes. These four probes are a matched set (same vintage, not collected from multiple sources). Teknicallythe 2465A would have originally come with two P6136 probes, but these are functionally identical. Having matched probes is important when you want to avoid time skew, and when you want to do A-B pseudo-differential measurements. All four probes come with grabber hooks, ground clips, and color ID rings. In one photo below you can see that the tips are only gently used and are still plenty stabby.Ottawa, Canada area. Shipping to USA/Canada is easy, quick, and relatively cheap ($30~$50). Elsewhere, it will be slow and expensive, but I'll give you a quote if you ask. I take great pride in packing delicate equipment as safely as possible.Asking $500 USD. Price is negotiable, especially if you want just the scope without the probes and front cover since they are quite valuable on their own.Payment by Paypal only.
