In almost every case, studio VTRs used Tektronix waveform and vector scopes. B&W picture monitors in VTRs tended to be Conrac, but most color picture monitors in Ampex VTRs were Tektronix 650 series.

If I am not mistaken, the big RCA 2” quad video recorders used by most studios had both a Tektronix waveform monitor and vector scope built into them. [email protected]> wrote:

The 524 series scope was designed specifically for measuring video signals. A later model – the 524AD – was included as part of the RCA station “package” (RCA demanded stations buy only RCA

Until Tek starting building their own CRT's in 1953, they were purchasing CRT's from RCA and Dumont, who were competitors. Tek wasn't getting the best quality tubes, so they made a point of putting

It is the standard graticle used to read a NTSC video waveform: the zero is, well, zero - the transition between video and sync the sync pulses are displayed below the line - ideally down to 40 the

Jeff, https://thediagram.com/17_3/waveform.html https://www.broadcaststore.com/pdf/model/793698/TT148%20-%204053.pdf https://download.tek.com/document/25W_7247_1_rfs.pdf These should help. I will

Video signal is coded as black ~ 10% (dashed line is at 7.5%, probably black level spec) white is 100%, sync pulses are at -40% (bottom half graticule). The reason for 0 to 100% and -40 to 0% ranges,

I couldn't find the listing. Can you make the pics available somewhere? Is it an ordinary vectorscope graticule? e.g. Tek 1720, etc. --Toby >

The probe and its termination (passive, 134, or 7A14) are designed as a system. As you can see in the P6021 manual, the Passive Termination box is a complex RLC network with several calibration

I'm not interested in this specific scope, but I grabbed the pictures for both the RCA affiliation, and the visible graticule, which I don't see mentioned on the TekWiki. I am almost completely

Will it work better with no termination box if I use a 50 ohm oscope input? What termination is it looking for?

You can also use a 7A14 plugin, IIRC.? It switches between probe types based on a ring, which is in a small adaptor that you attach to the probe. Compensation for both probe types is different.

The P6019/P6020/P6021/P6022 current probes MUST use either the appropriate termination box, or a Type 134 Current Probe Amplifier. Otherwise the frequency response will be poor since the probe portion

While searching, I stumbled over a kind of rare (I guess) item: a Tek 524D made for RCA: https://www.ebay.com/itm/175251862529 Not affiliated with the seller... Chris

I have a P6021 current probe but no termination box for it. Is the termination box necessary to use it and what are the consequences of not using it? What is the impedance of the probe output without

OOPS! Make that replaced with an MC68A02. My bad.

Jeff Dutky: I see MC68A02 and MC68B02 for sale on eBay, could you substitute one of those? I did just that and it worked perfectly. Thanks!

Ross, "ways to enable additional Bandwidth for some models"? Would this be for a 2465? How would I find out about this?

See if you have a LO feedthrough signal on band B near the left end of the scale. The A and B band use the same number pencil triode oscillator tube and you can swap the b tube in to get the a band

Hi, Yes, cal data is stored in the nvram. But I wouldn't worry much about it, as the 2432 is very simple to calibrate. By the time you solve the problem of saving and transferring the calibration data
