15. Z AXIS OUTPUT
This female BNC connector supplies a +5 V (nominal) level during retrace and band-switch intervals
of a step or list sweep. During step or list sweep, this female BNC connector supplies a -5 V
(nominal) level when the RF frequency is at a marker frequency and intensity marker mode is on.
This signal is derived from an operational amplifier output so the load impedance should be greater
than or equal to 5 kohms.1
Connector female BNC Impedance nominally 50 Ω
Signal A nominal signal level greater than 4 dBm.
