Look at the earlier messages, but... what you need is a computer w/HPIB that the Tek software sees. And that is more of the problem than anything else. Next ideally is a SG503 and SG504, a good DC standard and DC meter.
The 540B needs the DMM to do the 50ohm calibration. Everything else is read the pc screen and do what it says. I’ve never counted but each channel is calibrated on each range (4 steps each rage step) and then ch1 to ch2, ch1 to ch3, etc (12 steps each) then the time base is fairly straight forward about 25 steps for each of 2 programs. In other words long and boring. I’ve had 540Bs that took 3 min for each of the vert amp cal steps, then others that went in 30 Sec or so.
