Model AM5XT-200 / IEEE 743-1984 Standard /200kHz Bandwidth
Introduction
Ameritec’s AM5 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 AM5’s perform most standard tests,
worldwide. The AM5XT-200 meets all North
American IEEE 743-1984 standards.
The AM5eXT-200 meets international ITU
standards and is CE approved for use in the
European Community.
The AM5XT-200 and AM5eXT-200 operate
with a bandwidth of 20Hz to 200kHz. The
units can perform qualification tests on
circuits carrying voice band telephone, high
quality audio, DDS to 64KBPS, Basic Rate
ISDN, HDSL, or other services using up to
200kHz bandwidth.

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 unit’s 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 AM5 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 AM5 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 printer.
Fully Programmable Signal
Generator
Any frequency in the 20Hz to 200kHz band can easily
be selected at any level from -50dB to +10dB.
The following pre-set modes are available to facilitate
measurement.
• 1004Hz
• Loop Back Tone (Operator Pre-Settable)
• Slope Tones
• Frequency Sweep (With or Without SF Skip)
• P/AR Test tone
• ERL, SRL-LO, SRL-HI Tones for Return Loss
Measurements
• Envelope Delay or Group Delay Tones
• 4 Tone or 2 Tone for IMD Measurements
All test tones meet industry standards for purity and
accuracy.
The following measurements are provided:
*AM5XT-200 and AM5eXT-200 provide 200kHz Bandwidth

Use two sets for a complete
end-to-end test of 4 wire data
lines.
Use a single unit with an
Ameritec AM3 Series 4
Wire Responder for centralized loopback testing.
Use the AM5XT/eXT built-in
dial capability on dial-up
networks to access a distant
Ameritec AM3 Series 2 Wire
Responder or a second
AM5XT/eXT for centralized
2 wire testing.

Built-In Signaling
The AM5 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.
Remote Control
All front panel functions may be remote controlled by
simple ASCII character strings to the optional RS232 port.
There is even an “Auxiliary” port which can be used to
chain the AM5XT to a second device (for example, a
co-located test access switch such as the Ameritec AM6),
achieving dual control from a single terminal or computer.
When AM5XT units are used at each end of a line under
test, the distant AM5XT signal generator can be
commanded to recall test set-ups by sending DTMF
commands from the local unit.
XY Plotter Output
(option 25-0045)
Optional rear panel analog outputs are provided for
driving an XY plotter or strip chart recorder. This is
useful in graphing frequency response, plus group or
envelope delay results. This option is standard on the
AM5eXT-200 (CE).
Print or Plot Your Results
An accessory printer (Model AM-47XT) is available
for use with the unit. When connected to the optional
RS232 port, the printer can run a hard copy of any test
set-up and/or measurement result. When making
envelope delay, group delay or frequency response tests,
the “Print Lock” feature may be engaged for an
automatic printed record of the test results in both
graphic and numeric form.
Model 30-0033XT Signaling
Adaptor
The Model 30-0033XT is a Signaling Adaptor
packaged within the cover (lid) of an AM5 Series
Transmission Test Set or can be used as a stand alone
unit. It provides for Loop Start, Ground Start, DID and
Types 1, 2 and 3 E&M signaling. It also incorporates a
ring generator with manual cadence selection and
automatic ring trip. The unit supplies switch selectable -24
and -48 VDC line supply voltages and a switch to allow
for simulation of 1240 Ω loop resistance.
DDS/SW56 Loopback Test Set
30-0070 S:
The DDS Loopback Test Set provides CSU Loopback,
DSU Non-Latching Loopback, DSU Latching Loopback
and a Manual (or Forced) Loopback. DSU Latching is
accomplished with or without secondary channel.
The unit will transmit straightaway test patterns to the
distantend withmanual selectionof test patterns511,2047,
SP1, SP2, SP3, SP4 and SP5. Once again, Secondary
Channel is supported during all straightaway tests.
Supported data rates are 2400, 4800, 9600, 19.2K, 56K,
64K and Switched 56K bits per second.
Switched 56K testing is performed by connecting a
telephone butt set or AM5XT to the TIMS TX port to
provide ON/OFF Hook and pulse dial functions. Far end
signaling (wink, delay, answer) is indicated via front
panel LED.
HDSL Testing
With 200kHz bandwidth, the AM5XT-200 performs
full HDSL (High-bit-rate Digital Subscribers Line)
testing. HDSL provides DS1 (1.544Mbps) compatibility over two copper twisted pairs with each pair
carrying a 2B1Q full duplex data stream. These pairs
are tested configuring an AM5XT-200 to generate a sine
wave of 196kHz and then making the appropriate level,
noise and frequency measurements.
