    I have an older engine analyzer with a CRT that from what I found online was used in vector monitors. I already know where to input the signal to the vertical and horizontal deflection amp cards.

    Will the slower drawing rate version of the firmware work on that display? If so how can I get a copy of it?

    I’ve used this on several different older scopes (mostly vacuum tube operated) and it works well EXCEPT on scopes that use single ended deflection amps such as a scope that uses a 3AP1 CRT. That said even though those scopes do not go to 2 MHz I don’t know how high in frequency the deflection amps can handle.

    I use a Tektronix 606A X/Y monitor and had a similar problem. You will need to attenuate the ZINV output. Best way to do that is use a variable resistor of 10K or higher or lower (depending on the input impedance of the Z axis circuit) and set it until the picture looks proper. You can then measure the variable resistor and install a couple fixed resistors.

    I got a question. I want to add a series resistor to the X/Y outputs to protect them from accidental shorts. What is the smallest value resistor that I can use without affecting the display and that will not allow too much current through the chip if the output gets shorted to ground? I connected the clock to a scope and somehow shorted one output. Now the clock don’t work right.

    I have noticed a problem. On my clock whenever it is in PPS 1Hz mode the clock jumps from 0 to 1 seconds in less than a second which makes the clock gain a few seconds in under an hour. Now if I use PPS 4096 mode it don’t do that. Is there a way to fix it as I don’t want to have to select PPS 4096 mode each time I power up the clock. I have the latest firmware installed as well.

No public wish lists :(
