Test Sequence Output Outputs a TTL signal which can be set to a TTL high pulse (default) or low pulse at
end of sweep; or a fixed TTL high or low. If limit test is on, the end of sweep pulse
occurs after the limit test is valid. This is useful when used in conjunction with test
sequencing.
Test Set Interconnect 25-pin-D-sub (DB-25) female; use to connect the lightwave test sets
Measure Restart Floating closure to restart measurement.
External AM Input
±1 volt into a 5 kΩ resistor, 1 kHz maximum, resulting in approximately 2 dB/volt
amplitude modulation.
