NOTE
Calibrator pulse modulation can also be supplied by an external pulse generator via the rear-mounted BNC
connector labeled ―EXT PULSE‖. Select ―Ext‖ in the Calibrator > Pulse > Source menu window. TTL-
level signals connected at this input port will gate the 1 GHz calibration signal on and off. A low level
signal turns the RF output off.
