Agilent Technologies E8285A manual Access Probe annunciator, AC Level

Chapter 4, Description of Fields

Fields

Access Probe (annunciator)

This annunciator lights when the mobile station transmits an access probe. This annunciator will remain lit until the call has been terminated.

A sequence of access probes is transmitted as part of the mobile station’s attempt to gain access to a CDMA system. A mobile station originated call or a mobile station terminated call each require the mobile station to transmit access probes.

GPIB Example

“DISP CCNT;STATus:CDMA:COND?“

queries the CDMA condition register. Bit 0 will be set when the Access Probe an- nunciator is lit.

AC Level

This is the default measurement for this field. The type of measurement shown is dependent on the AF Anl In settings.

This measurement displays either rms potential (voltage) or audio power (Watts or dBm).

GPIB Example

“DISP AFAN;AFAN:INPUT ‘SSB Demod’;:MEAS:AFR:ACLevel?”

selects the AF ANALYZER screen, selects single-sideband demod from the AF Anl In field, then queries the AC Level field.

Operating Considerations

When the unit-of-measure is changed to measure AF power, the external load resistance must be specified. See Ext Load R field description, on page 256.

The input for the ac level measurement on this screen is always the AUDIO IN connectors.
