Magnus, I was unable to respond to your message earlier; too many visitors & too many diversions.
Thanks for the info on the CNT-91; I have read the datasheet thoroughly and it would be VERY nice to own one, but too many $$ for me. I have downloaded the evaluation copy of Timeview. It works well, but without any capability to save/store results, it's only a toy for me. I can't justify the $395 license fee since I'm retired. Oh, well. I have a licensed copy of HP VEE 5.0 (now quite old), but it does allow me to operate my CNT-81 from GPIB and save data for later processing. Using the internal (block) function I have been able to capture TI data at 6Kpoints/sec, but records have to be limited to 4466 points per capture. Still, this is useful. While learning to use my CNT-81 I was surprised to discover a minor, but possibly important anomaly in it's performance. I was attempting to discover the best case jitter measurements which could be taken on stable sources at 5, 10 and 100MHz. For the 5 & 10 MHz sources, the jitter consistently reads < 22ps for large & small samples. At 100MHz I was expecting jitter results as good, or better than those at lower frequencies. But, this was not the case. The jitter results were >40ps! After consulting the folks at Pendulum, it was confirmed that input signals near the internal 100MHz reference cause period measurements to exhibit 240ps peak-to-peak jitter at 10x the frequency delta of the reference to the input. I have screen shots of Timeview analysis if you're interested.
