Jim, I was one of those HP/Agilent field cal guys doing the MTE, never did it for Raytheon, but did it for 100’s of other customers. We verified that every instrument made published specs - no

Hi Mark, Very nice to see you here! Your review article on sampling scopes is a true classic. I blame and thank you for the happy hours I've spent trying to chase down and then read, all the

Another youtube video, min 9:25, 7s12 finding for a broken wire inside a rope memory from apollo guidance computer:

Sure, important and interesting. Is there a special relevance to the point I was trying to make? AFAIK, the architecture and hardware are the same across the whole family, incl. the TDS3064 600 MHz

I can't resist commenting about: "If there is a network theorist left on your faculty (very rare these days)," In fact, it appears that circuit theory classes have nearly vanished. One of the few I

Hi Sean, I remember now. My 7104 spends most of its time, all dressed up, with no place to go... So, it is not one of the scopes that I am most familiar with. If you look on the front panel, you will

Another thing you may want to compare is the "effective bits" vs frequency. Ed

I thought if one clicked on the user it brought up the E mail reply. Contact <shalopt@... >

Chuck, Looks like mine has a more modern readout board, that contains no switch. It has a large socketed ROM where the switch would be in an older style readout system...the plot thickens... Sean

After the 4041 console has changed to the COMM0: serial port on the back of the 4041, you then use a terminal emulator program on your PC and a USB to RS-232 serial adapter to send programs to your

I realize "step response" is the term commonly used. During adjustment/calibration, step response is made to follow the applied electrical voltage step as accurately as possible. Some overshoot is

Chuck, Good call; I should open it up and take a look. I'm not sure where the readout board even is on a 7104...the internal layout is *vastly* different compared to the 7904(a)! Sean

I think I have a solution to the 4041 tape issues - I call it my 4041 Console Commander :) My Console Commander is a tiny Arduino module connected to and powered by the 4041 keyboard connector with

Another gotcha (that is really really expensive) are the 50 ohm female loads that came in 3.5mm cal kits made by HP. They contain super tiny "fingers" inside that help with the match. One flinch while

What do you mean, adjusting the step behavior?

You can't appreciate them, unless you appreciate the math. I think they were first used in pulsed RADAR ... but the 500 series based samplers were used in early Cold War Nuclear research. Reg is the

Inspired by recent postings in this group, I've decided to describe my experience with a TDS3054 and a TDS3054B. These 'scopes have a published bandwidth of 500 MHz on all channels. The TDS3000-series

Yes.. that's it... you can't forget that screen. Thanks for the video. I've got 7S11 and 7T11 in a 7603, and some sampling heads...but, I don't know where... and I haven't fired it up for a few years.

Typo: “SG503” should be SG504. The former does the sensing inside the instrument and obligates you to buy an expensive cable to keep leveling quality all the way to the end of the cable. The SG504

Thanks Jon but I am not looking for accurate calibration.? After reading the manual a few times I see there are three adjustments for each channel.? So when I feel motivated I will look for them and
