Hey y'all,
I'd like to do a full perf verification and possibly calibration of my 2467 - I'm pretty sure I messed her up a bit during and after the repairs I did. Also, I'd like to know that I can do this in the eventuality of her losing the NVRAM.
I have some of the gear listed, like a pair of SG503/504. Other gear I have handy are a PG501, and an FG503 that I've recently overhauled. I also have access to a Siglent DDS function gen that goes to 3MHz.
In addition to those, I have my handy-dandy 2430, whose vertical "deflection" is calibrated against my Fluke 87, and whose horizontal is referenced against its internal crystal oscillator.
So, I figure I could set up the required test signals measured against the 2430, and use them to test/calibrate the 2467.
I also have my TDS784D (the truck), and while I don't trust her calibration particularly, I can at least use her as a frequency counter above the 2430's bandwidth. I suppose I can also measure her vertical against DC inputs to see where she's at - the horizontal shouldn't be in question? In high-res mode she goes to 15bit resolution, which is a couple of orders of magnitude above the +/-2% deflection accuracy of the 2467.
Now, it looks like the time marks for the horizontal go from .5s to 2ns.
On a PG506, the 5/2/1ns outputs are a sine wave anyway, and I figure the FG504 can supply that, so long as I can measure it accurately enough to the correct frequency. The lower frequencies are not a problem for the PG501, though I wonder how stable the output of the PG501 is going to be. I figure it'll probably be stable enough as the 2467's sweep is all analog anyway?
It looks like for the vertical, the calibration voltages go from 20mV to 10V peak-to-peak, which shouldn't be a problem for the FG503 (or the Siglent).
One thing I know is missing is transient response, as I don't think any of the gear I have access to has a fast enough "known" edge to measure that against.
What else am I missing - if anything?
