Situation:
The 8922P/X #H09/K09 is a customer/Agilent installable retro-fit for testing of mobile phones
capable of supporting Multi-Slot Data. Firmware should be C.01.06 or higher for this
option. This option uses two 8922Ps operating as a system in a master/slave combination.
The timing information required to synchronise the two instruments is sent between the
system bus connectors of each instrument via a cable supplied with the upgrade kit. Should
the need ever arise to check this port the following checks will verify instrument operation at
the system bus connector.

Solution / Action:
Service Information for verifying signals at System Bus connector. Output at pin 5 using
DMM (Pin 5 normally TTL hi level).
Check 1
Set service latch ’g_run_reset_cntl = 0’ on service screen.
Pin 5 should be at UL 0.8 VDC, LL 0 VDC.
Check 2
Set service latch ’g_run_reset_cntl = 1’.
Confirm Pin 5 high, ie voltage UL = 5 VDC, LL= 2.4 VDC.
Input level to pin 3 using DC level
Check 3
Apply lo level (0.5VDC or ground) to Pin 3.
Confirm error ’Call disconnected:Ph error:0x009f’ is seen on instrument screen
Check 4
Apply high (5VDC) to Pin 3
Confirm no recurrance of error ’Call disconnected:Ph error:0x009f’ on screen
Output at pin 24 using DMM (Pin 24 normally TTL hi level).
Check 5
Set service latch ’g_ext_trig_out = 0’.
Pin 24 should be at UL 0.8VDC, LL 0 VDC.
Check 6
Set service latch ’g_ g_ext_trig_out = 1’.
Confirm Pin 24 high, ie voltage UL = 5 VDC, LL= 2.4 VDC.
These checks confirm operation of the signals at the system bus connector.
