OPERATION CAL/ZERO MENU

RF ON/OFF Turns the RF calibrator ON or OFF. [RFCAL]

Ext V Zeros the rear panel multi-purpose BNC connector used for Volts per GHz con-

[VZERO] nection (Analog Input). This will calibrate the units to read zero volts on this BNC. During this operation the connector should either not be connected to anything, or should be connected to a 0 Volt source.

The rear panel voltage can be viewed by selecting CHANNELINPUTVOLTS, al- though this does not have to be selected in order for the function to operate.

This calibration is non-volatile and does not normally need to be performed. In the case of offsets being introduced by the user’s setup, it is possible to leave the BNC cable connected to zero out system offsets, however the offset zero range is limited to approximately 100 mV.
