Operations
These are descriptions of operations which may be unclear to the user as to how they
occurred. These are NOT defects.
1 The Agilent 8922M/S occasionally sends ABORTS to the attached protocol mon-
itor. These ABORTS are normal and logging data is not lost.
2 In the FA and SD/4+FA control channel configurations, the Agilent 8922M/S
sends speech frames rather than fill frames on the FACCH when there is nothing
else to send.
3 The DRX ON mode corresponds to the NORMAL paging mode. The
Agilent 8922M/S sends continuous paging mode NORMAL on the idle PCH
blocks. The DRX OFF mode corresponds to the REORGANIZE paging mode.
The Agilent 8922M/S sends continuous paging mode REORGANIZE on the idle
PCH blocks. When in the REORGANIZE paging mode, the Agilent 8922M/S is
guaranteed to page on a random PCH block which is not the block expected in
the NORMAL paging mode. The active PCH block will page the MS with the
paging mode set to SAME. The SAME mode means “the same paging mode as
last indicated.”
4 TMSI reallocation in the Agilent 8922M/S uses the two (2) octet TMSI size.
5 The Agilent 8922M/S does not turn off the transmitter during DTX when the
voice activity detector (VAD) determines that there is no speech input present.
Instead, the Agilent 8922M/S sends a silence descriptor (SID) on every speech
frame.
6 USE MEM is not intended to be used with Pulse (Pulse ON/OFF Ratio)
measurements - do not select USE MEM after making a pulse measurement.
7 During a Pulse (Pulse ON/OFF Ratio) measurement the following message can
occur if the device under test is generating a larger signal than is expected: ‘RF
Overpower occurred during Pulse On/Off Ratio measurement’. This message
cannot be queried via GPIB. Use the Hardware 1 Status Register Bit 5 to detect
this condition when doing pulse measurements.
NOTE Option 006 (spectrum analyzer) must be installed to make pulse measurements.
8 The Output RF Spectrum measurement and Pulse On/Off Rise and Fall
measurement results shown on the Main view screens are not accessible via
GPIB or IBASIC. These measurement results are available on the Trace view
screens. All GPIB and IBASIC actions with these fields refer to those fields
shown on the Trace view screens.
