LCL Balance Measurement with ET 91
Two balance measuring modes are provided:
■ Measurement with one single frequency
■ Measurement in sweep mode
ET 91 performs LCL measurement using the test circuit described in ITU-T Rec. 0.9
Selectable ranges
Test results are available in graphic or numeric formats.

Quick Frequency Response Test of ET 91 with
Multi Tone Test Signal
Selectable ranges
MTTS METHOD:
ADVANTAGES:
■ The transmitter generates 35 test tones
■ The receiver measures the 35 test tones simultaneously
■ No synchronisation is necessary between the two instruments
■ The measuring time is shorter than that of other methods

Micro Interruption Measurement with ET 91
An interruption is detected when the level of test tone drops below a designated threshold for
more than 0,6 ms. The detected interruptions are included into five categories by duration
