Bob, I'm the Tektronix Application Engineer who posted about this topic about a month ago. Sorry for the delay in responding to your question about the B channel divider feature.
Since the TVC501 measures period, it will have a very low resolution when measuring higher frequencies (such as 10 MHz). Using the divide by 1000 feature produces a proportionally greater resolution. The offset feature allows the high count to be translated down to the D/A converter range, so that moderately small changes in that frequency are converted into voltage changes. The TVC501 was introduced when analog (and early digital) oscilloscopes didn't have time qualified triggering. One key use for this instrument was to provide an analog trigger signal for such oscilloscopes based on period or time internal. Another use was to allow the user to use an oscilloscope to measure the settling time behavior of PLL's up to the divider maximum input frequency. My office is moving over the next month or so to a new location. Since the TVC501 was introduced before PDF and other user document formats were available, I'm pretty sure I don't have some old floppy disk with support documents. I would have to get assistance from others to read a floppy disk these days anyway! There is a small possibility that I have some old printed TVC501 application information which didn't get discarded during my last office move, and I will look for any such material during our move. -- Bill Byrom N5BB On Sat, Jun 27, 2015, at 12:24 AM, Robert Gilchrist Huenemann wrote: > I have received the manual for the TVC-501 plug in.
