The
Comtest X21H has a 15 pole dual in line switch with DCE/DTE sockets on both
sides, making it possible to break and crosshatch all lines by means of the
switches and jumper cables. The two dual gender ribbon cables assure 100%
connectivity in any type of configuration. All contacts are gold plated to
ensure good electrical contact.
The
six in-line monitor test signal strength according to the V11
standard (t.e.: 200mV). The Signal Strength circuitry allows to
test more realistic level of 0./0.6/1 and 2 Volt. Pulse traps
increase the functionality of the extra monitors.
The
Ground Potential Difference test is an important feature needed if
different grounds (wall outlets) are used. The “in line” GPD
tests for voltages over 2 volts, the unassigned monitor/trap
allows test of Ground Potential Differences as low as 0.3
volt.
The
Comtest X21H runs over 120 hours on two AA 1.5 volt batteries
or external adapter. The 1.5 volt source is provided by a separate
AAA size battery and galvanically separated.
It
is housed in a ABS plastic case. The logical face plate is easy to
read and gives all information needed to test the X21 interface.
Size of the main unit:
150 x 105 x 20 mm Weight: 295 grams.
