LOCAL OPERATION

Rx = Tx Offset Freq:
A setup option within the Tx TEST mode (Rx=Tx) will set the signal generator used for receiver
testing to the measured frequency of a transmitter being tested. An Rx=Tx offset frequency
entered here will cause the signal generator frequency to differ from the measured transmitter
frequency by the offset frequency. To enter an offset frequency, press the adjacent soft key, key
in the appropriate digits, using the minus key and the decimal point key if necessary, then use the
relevant terminator key, (MHz, kHz or Hz). A positive figure will set the signal generator
frequency above the measured transmitter frequency, while a negative figure will set the signal
generator to a lower frequency than the transmitter.
RF Level in:
The selection is made by toggle action of the soft key. The PD or EMF flag is shown against
output levels displayed as voltage or dBµV.
With the EMF option selected, the displayed RF output level shows the open circuit voltage
available at the RF output connector.
With the PD option selected the displayed RF output level shows the voltage that would be present
across a 50 Ω load.
