HP (Hewlett-Packard) HP 16510B TV Converter Box User Manual


 
Probe Cable 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.
Caution 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.
