Tektronix 7603/7L13 Calibrator accuracy...? /Ailtech 460
It should be as accurate as the 7L13 instrument itself. Note however that given their age, each 7L13 today most likely requires full calibration to achieve the factory specs. I had to calibrate mine,

If you're bored and have a 7000 series scope
I've done this trick with two timebases in my 7854 to display the vintage MDA (Hercules monochrome) PC graphics card output on the scope CRT. It is readily doable, but tricky due to the following: - T

Connecting the Tek 7854 to a modern PC
Hi Everybody, 7854 is too awesome to retire just yet. It's unique digital features were not easy to access from the outside for a long time due to expensive GPIB hardware and lack of software support

Hi Bob, You did not mention using any termination in your setup. Your HP 8657B performance is specified only if terminated with 50Ohm. Even if you did use an external 50Ohm terminator with your Tek 24

Mechanism of CRT Double Peaking (UPDATED)
Hi Jeff, 5103N appears to be only the module mainframe, separate from the CRT unit. However I found the CRT circuit to be similar (if not identical) among the 5000 series models, so no problem there.

Hi Chuck, Yes, I agree we derailed the subject by going deep into the cathode issues, but I still instinctively believe that double peaking explanation may be within grasp (without major research). Un

Mechanism of CRT Double Peaking (UPDATED)
Perhaps my statement wasn't precise enough, I meant to say "if the interface layer was behind the double peaking phenomenon...", not question the interface layer existence per se. Oxide cathode is so

If the "interface layer" theory was true then the same negative resistance phenomenon would also be observable in conventional tubes. Personally I've never seen one behave like that, although I curve

Spectrum analyzer Tektronix 7L13 on mainframe Tektronix 7603
The eBay ad is a mess but the device is decent, well worth it but won't do wonders for $20. It's a white noise source, just a plain Zener diode hooked to a wideband amplifier. Reference (average) leve

Using 7L* SAs in 7854 is a song. It's not just the digital storage, it's the averaging that can significantly help smooth the measurement and increase your SNR. I do it all the time with my 7L5 and al
