ARGUS 152
Interchannel delay
The ARGUS will send the B channel data to a loopbox which will then send it back on the
same channel. The ARGUS measures the propagation delay for the data on each of the
B channels and determines the difference between the two propagation delays
(interchannel delay). If the ARGUS does not receive the data back in the B channel in
about 13 seconds, it will display the message “No loop”.
The measurement (continuous measurement) must be terminated manually.

Perform measurement
Display:
The measurement will be repeated in
cycles (continuous measurement).
avg: average interchannel delay
min: shortest interchannel delay
max: longest interchannel delay
bit:
The average interchannel delay in
bits (multiples of the time required to
send a bit at 64 kbit/s, it takes 15.26
µs to send a bit).
Stop measurement, the ARGUS will
display the last measurement.
