Agilent Technologies 8935 series e6380a manual Base Freq User Defined, Beeper

Configuration - Screens and Control Fields

Control Fields on the Configuration Screens

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.

Screen(s) Where Field is Present

INSTRUMENT CONFIGURE

Beeper

This field changes the audio beeper volume by selecting the desired level from a list of choices (Off, Quiet, Loud). The beeper always beeps when the instrument is turned on, regardless of this setting.

Operating Considerations

The beeper alerts you any time a message is displayed. Since a message may be removed from the screen before you notice it, it is better to leave the beeper on to alert you to errors during operation.

The beeper’s volume setting is retained when the instrument is turned off.
