TEST SEQ. This outputs a lTL signal that can be programmed in a test
sequence to be high or low, or pulse (10 pseconds) high or low at the end of a
sweep for a robotic part handler interface.
Pass: 'ITL high
Fail: Tl'Llow
VGA OUTPUT. This provides a video output of the analyzer display that is
capable of running a PC VGA monitor.
Source Group Theory
The source functional group produces a stable output signal by phase locking
a YIG oscillator to a synthesized VCO (voltage controlled oscillator). The full
frequency range of the source is generated in subsweeps by harmonic mixing.
The output is a swept or CW signal with a maximum leveled power of + 5 dBm
(-10 dBm, HP 8722D) at the front panel measurement ports (minimum -65
