Measures to 120 kHz. For a 200 kHz bandwidth please see the
Ameritec's AM5XT series of Wideband Transmission Test
Sets are engineered for peak performance in the field and the lab.
They offer a full range of transmission impairment measurements, a
highly versatile signal generator and basic telephone signaling in
a single compact, portable unit.
The Ameritec AM5XT Wideband transmission test set
designed for use in the field and lab. Performs qualification tests
on circuits carrying voice band, HDSL, high quality audio, DDS to
64kbps, Basic Rate ISDN and other services using up to 120kHz
bandwidth. This model meets North American IEEE 743-1984 standards.
Measurement Capabilities Include: dBm level or dB loss Frequency
& Frequency Response (Attenuation Distortion) Noise & Noise
w/tone (Wideband or with Filters) Signal/Boise Ratio (wideband or
with Filters) Noise to Ground (Wideband or with Filters) Impulse
Noise (Wideband or with Filters) Phase or Amplitude Jitter Group
and Envelope Delay 2- and 4-wire Return Loss
Ease of Operation/Store and Recall
The front panel is arranged as a 5 x 16 push button
matrix which allows simple control of all line, send, measure,
auxiliary and signaling functions and still allows the operator to
view the units configuration at a glance. No need to scroll or hunt
through confusing menus. For simplicity of operation, up to 40 test
set-ups can be stored in non-volatile memory for instant recall.
The complete test set-up is always displayed, but operation is
simplified to a few keystrokes. When using a pair of AM5XT series
units, the local unit can exercise remote control over the distant
unit through test set-up recall commands issued over the line under
test. An extensive Help Directory in memory can be viewed or
printed via the optional RS232 port.
Audio Monitor and Speaker Phone
The built-in speaker allows the operator to audibly
monitor either the send or receive line under test. A built-in
microphone provides Speaker Phone or Push to Talk operation over
the line under test.
Field, Lab or System Use
The units fit anywhere. Use the basic unit as a
bench top laboratory instrument, or, with the addition of internal
sealed lead acid battery pack and soft case, as a highly compact
field instrument. Battery capacity provides for up to eight hours
of uninterrupted use between charges. If your application dictates,
add the optional rack mounting kit and RS232 remote control port
and integrate it into a system for network testing.
A Wide Variety of Measurements
The Ameritech AM5XT series performs all common voice/data
analog transmission tests. All measurements are fully auto-ranging
and may either be viewed on the bright LED display or output to a
The Ameritech AM5XT series units are unique among
most transmission test sets in that they provide basic loop start
line signaling. They include separate On Hook/Off Hook DC Hold
Circuits for Send and Receive Line and the ability to signal using
Dial Pulse, DTMF or MF(R1). This feature is useful in testing
dial-up circuits or in commanding responder devices (such as the
Ameritec AM3 Series) on 4 wire dedicated circuits.
