Base Freq (User Defined)

The Base Frequency field sets the RF Generator reference for channel 0 (zero) when the RF Chan Std field is set to USER-DEF, and the RF Display field is set to Chan.

Channel frequencies are calculated using the following formula:

Channel N = Base Frequency + (N)(Channel Spacing)

The Base Frequency is calculated using the following formula:

Base Frequency = Channel 1 Frequency - Channel Spacing

For example, if your multi-channel radio’s lowest receive channel frequency is 870.030 MHz and the system channel spacing is 30 KHz, you would enter 870 MHz in this field. You would also use the Chan Space and (Gen)-(Anl)fields to tell the Test Set where other transmit and receive channel frequencies are in relation to the base frequency, and whether or not the system is duplex.

Operating Considerations

The value of this field is only used if the RF Display field is set to Chan, and the RF Chan Std field is set to USER-DEF.
