Fields

RF Chan Std

This field is displayed when Chan is selected in the RF Display field on the

CONFIGURE screen.

Use the RF channel standard field to select the channel standard for the radio- under-test. The RF Generator’s and the RF Analyzer’s frequencies are automatically set to correspond to the channel number entered in the RF Channel field.

Some of the RF Chan Std choices require that the Test Set is configured to operate with a specific Agilent Technologies 83236 model (table 16 on page 366). The choices displayed will be limited to the RF channel standard’s your hardware is capable of providing. If you do not know if you 83236B is equipped with Option 007, one way to find out is to query the Test Set using the GPIB Common Command, *IDN? (refer to the E8285A Condensed Programming Reference Guide for a detailed description of this command). If you have Option 007, the word “WIDEBAND” will be included in the string returned by the Test Set.

GPIB Example

“DISP CCNT;CONF:RFCS’USER-DEF’

selects a user-defined RF Channel Standard, The base frequency, channel spacing, and offset between generator and analyzer frequencies are settable on the Config- ure screen when USER-DEF is selected. “

Operating Considerations

For the NAMPS standards, a third letter is added indicating which frequency band is used: upper, middle, or lower. For example, when testing a mobile station using the lower band, choose MSL NAMPS.

The USER-DEFselection is used to define your own channel assignments. When USER-DEFis selected, you enter the Base Freq, Chan Space, and (Gen)-(Anl)settings, found on the Configure screen.
