Signal Descriptions for SYSTEM BUS

RP_DMOD_TRIG Pin 7 Input

This is the rear-panel trigger signal input for digital demodulation. It connects to the DSP analyzer. It can also be used for other triggered measurements.

This signal is active when the digital demodulator’s demodulation trigger source is set to Ext Demod, or when the measurement synchronization trigger source is set to Ext Demod.

Requirements Amplitude: TTL levels High drive requirements: 100 μA Low drive requirements: 2 mA Active edge: rising edge.

RP_GSM_RST_IN

Pin 3 Input

 

 

This connector is an active low input that halts and resets the Agilent 8922 GSM

 

counters (frame, timeslot, and bits). It is used when two or more Agilent 8922M/S

 

are connected together (daisy-chained) to simulate a GSM system.

 

Requirements

Amplitude: TTL Levels Low Drive: 100 μA High Drive: 2 mA

 

 

Active Level: Low

RP_GSM_RST_

Pin 5 Output

 

OUT

This connector indicates whether the Agilent 8922M/S GSM counters have been

 

 

halted (by RP-GSM-RST-IN). It is always active (TTL Low) when the Agilent

 

8922M/S is in the Settable Mode.

 

Requirements

Amplitude: TTL Levels Low Drive: 100 μA High Drive: 2 mA

 

 

Active Level: Low
