Keysight's DSL TIMS modules for the Service Advisor test tablet provides comprehensive testing in a flexible, versitile tool for evaluating outside plant, line qualifications, physical layer testing, and troubleshooting.

Line Qualification Test Sequencing

For analog services including VF-POTS and Modem.

Signal Frequency, Level, and Attenuation

Frequency sweep provides fast wideband results that can be viewed simultaneously on the large display providing easy-to-read results at a glance.

Noise Tests

Perform noise or noise with holding tone tests, impulse noise, noise balance, and noise to ground tests. View level, low, middle and high.

23-Tone Transmission Tests

Powerful voice band measurement tool including level, signal-to-total distortion, signal-to-noise ratio, second and third order intermodulation distortion and envelope delay distortion.

Load Coil Detection Tests

Detect load coils on the loop prior to installing DSL.

Internal Noise Impairments

More powerful than weighted noise measurements, this module can be used to find noise created by other services on the same cable, iIdentify nosie and interference sources and verify proper modem transmit spectrum.

Phase Hits, Gain Hits, and Dropouts

Easily set threshold and pass/fail criteria for each parameter. View numeric and graphical "meters" simultaneously.

Analog Signaling

Supports loop-start trunk and, monitors signal states.
