8568b YTO problem
I have three 8568B SAs. One works fine, the other two have the same
8568B - 2503A01022.
Test FX = 441.0 Mhz -10db. (freq and cal readout are right on)
Span 1 Mhz ok - no jitter (pic 1mhz)
Span 1.1 Mhz - jitter (pic 1.1 Mhz) (no YTO Icon)
Span 20.0 no jitter
Span 20.1 Jitter and YTO icon. (pic 20.1Mhz)
Pictures are on my dropbox - taken with Trace in "Max Hold" to show width
I have the complete set of manuals - Troubleshooting and performance tests.
Any suggestions on what section to start?
Any help would be appreciated!
