Probes: Have you considered a Fluke PM9100/101

High voltage probes with a 100:1 transfer ratio. Cable length 1.5 m. High input impedance (66,7 Mohm) and high isolation voltage of the tip allow measurements up to 1000 V CAT III or 4 kV on Type 1 circuits (Type 1 circuit has it's primary in installation category II). Equipped with command switch and range indicator (/191 only).

• Models:
  
  • PM 9100/101 100:1, 200 MHz, 1.5 m, 66.7 MΩ / 3 pF, 1000 V CAT III **, Range 15 to 35 pF.
    
    • PM 9100/191 100:1, 200 MHz, 1.5 m, 66.7 MΩ / 3 pF, 1000 V CAT III **, Range 15 to 35 pF, with Command Switch and Range Indicator.
      
      • ** 1000 V CAT III or 4000 V type 1 circuit
        
        • Each probe consists of:
          
          • Probe cable assembly,
            
            • Probe body,
              
              • Retractable hook tip,
                
                • Ground lead and clip,
                  
                  • 6 colored identification rings.
                    

They're discontinued, but still available used.

I'm definitely covered at this point.

I think a probe that can do differential measurement of 5.6kV should definitely cover the KGVHV amplifier.

Here's the square wave of my Tek CFG280, notice the time scale (100ns). 19ns rise time isn't bad.

Nice scope. Did you get a good deal on it?

[luvdunhill]

Nah, not really. Given the options and condition and accessories I probably paid a bit above market value. I'd never go back though, it's a really nice setup.

Necro bump, is the Rigol DS1102E still the best entry level DSO to buy? I looked into some of the other Chinese OEM stuff but they're not as well documented or supported, it seems, and some people had issues with glitches. Currently using Tektronix 455.

Anyone had any experience with BK Precision scopes? (Positive or negative)

The 2542B-GEN model currently is very attractive as it has a built in signal generator.

That said, a similar Rigol with a Rigol standalone signal generator is comparably priced or even slightly cheaper. Might even be able to bump to 200MHz-2G/s for a few dollars more.

Or just say screw them both and save up for a Tek?

I have a Hantek DSO2150 USB scope. It has 150MS/s and 50MHz claimed if you only run one channel. It cost me £129.98

or $210 US, whichever makes the most sense to you.

It's about as cheap as you can buy anything new claiming a 50MHz B/W.

I like it.

I like it better than a Picoscope. The nice thing about a Picoscope is that it's self-contained. I mean the ones with the self-contained probe, like a USB toothbrush. Handy and robust enough to keep in a laptop bag stuffed in with a few pliers, wire strippers, side cutters, crimp tools, crimps, connectors, screwrivers straight and crosshead, multimeter, cable tester, Allen keys, soldering iron, solder, spare cables, USB RS232, card reader, torch, loupe, camera and whatever is the order of the day. I put the Swiss Army knife in the suitcase in the hold for international travel.

I used some very fancy 'scopes, too.

Logic analyzers, spectrum analyzers and network analyzers. I did a year of release test on military digital radios at Racal, now Vodafone, for my student placement, the last 3 months developing ATE in the Lab writing HPBasic, the forerunner of Labview, to run test racks over IEEE 488 (GPIB).

I know wherof I speak.
