Tektronix TDSCPM2 User manual
Getting Started with TDSCPM2
You can use this side of the Quick Reference to start to take
measurements with the Communication Pulse Measurement
Application (TDSCPM2). The other side contains a
complete menu tree for the TDSCPM2 application.
NOTE. For complete operating instructions
and General Safety information, refer to the
Online Help for the application.
The TDSCPM2 application is the third generation Digital
Interface Test System (DITS) technology from Tektronix.
The application helps you to test if your communications
signal meets the compliance test requirements of the
telecommunications industry for low speed electrical
interfaces. The application supports the ITU--T G.703 and
ANSI T1.102 standards.
Performing a compliance test
1. Use an AMT75 differential signal or AFTDS 75/50 Ω
electrical interface adapter to connect the device under
test to Ch1 of your oscilloscope.
2. Push the Autoset button on the front panel of the
oscilloscope. The oscilloscope displays the signal to test
for compliance.
4. Select an Industry Standard and Data Rate.
5. Select the Pulse Amplitude test in the Select Test area.
6. Push the “Running Man” button to start taking
measurements.
Generating a Compliance Report
To produce a compliance test report, select Log > Statistics.
Automating the Test Process
You can automate Compliance Testing through GPIB
control of supported oscilloscopes.

TDSCPM2 Ordering Information
This application supports TDS5000B, TDS6000B,
TDS6000C, TDS7000B, TDS7000, CSA7000B,CSA7000,
DPO7000, and DPO70000 series oscilloscopes; refer to the
Optional Applications Software on Windows Based
Oscilloscopes Installation Manual foralistofspecific
models. The applications CD includes a PDF file of the
installation manual.
If you order Option CP2 with a new oscilloscope:
H Communications Pulse Measurements Application is
installed and enabled
To order an upgrade for an existing oscilloscope:
H Order the TDS5BUP Option CP2
H Order the TDS6BUP Option CP2
H Order the TDS7UP Option CP2
H Order the CSA7BUP Option CP2
H Order the CSA7UP Option CP2
H Order the DPO7UP Option CP2
Option SM, Serial Communication Masks (standard on CSA
and optional on TDS) is required.

3. Select File> Run Application> Communications Pulse
Measurements 2 in the TDS oscilloscope menu bar or
Analyze> Communications Pulse Measurements 2 in the
DPO oscilloscope menu bar.
7. To perform a complete suite of compliance tests, repeat
steps 5 and 6 for the Pulse Imbalance Variation, Spectral
Power, and Mask tests. The figure below shows an
example of the final result.
NOTE. The CP2 option is not available on
TDS5000 or TDS6000 series oscilloscopes.
Recommended Accessories
AFTDS -- Telecom Electrical Interface Differential Signal
Adapter
AMT75 -- 1 GHz precision 75/50 Ω Adapter (5x)
NOTE. To ensure the proper impedance
termination for DS1 signals, it is highly
recommended that you use ADC, part number
CCCBSMB04 (precision 100
cable) with the AFTDS adapter.
