Probe Cable

Caution

The probe pod cable contains 17 signal lines, 34 chassis ground lines and two power lines that is woven together. It is 4.5 feet long.

The probe grounds are chassis (earth) grounds, not "floating" grounds.

Each cable is capable of carrying 0.67 amps for preprocessor power. Current in excess of 0.67 amps per cable will cause the preprocessor supply voltage to drop below a safe level. DO NOT exceed this 0.67 amps per cable or the preprocessor may malfunction. Also, the maximum power available from the logic analyzer (all cables) is 2 amps at 5 volts.

Note

The preprocessor power source is fused. The fuse is located inside the HP

 

 

 

 

 

16500A on the logic analyzer card. If a preprocessor appears to be

 

 

 

 

 

 

 

 

 

 

malfunctioning, refer to the HP 16510B service manual for instructions on

 

 

 

 

 

 

 

 

 

 

checking this fuse.

 

 

 

 

 

 

 

 

 

 

 

The probe cable connects the logic analyzer to the pods, termination

 

 

 

 

 

adapter, or the HP 10269C General Purpose Probe Interface.

Probes Each probe is a 12-inch twisted pair cable and is connected to the probe cable at the pod. One end of each probe has a probe tip assembly where the input R-C network is housed and a lead that connects to the target system. The other end of the probe has a two-pin connector that connects to the probe cable.
