TEST LIMITS:
Enables or disables the test limit(s). Toggle the
Test Limits
soft key between
On
and
Off
.
HIGH LIMIT:
Sets the upper limit. Use the numeric keys to input value and press the unit soft
key or the
ENTER
hard key to complete the input.
LOW LIMIT:
Sets the lower limit. Use the numeric keys to input value and press the unit soft
key or the
ENTER
hard key to complete the input.
PHASE ERROR PEAK:
Sets the peak of the phase error (in degrees) between the measured
phase and the ideal phase of a TCH timeslot, at a single instant. The GSM standard specifies the
peak phase error not to exceed 20 degrees during the useful part of the GSM burst.

EVM RMS:
Sets the RMS of the error vector magnitude, which is measured and calculated over
the useful part of the burst, and is shown as a percentage.
