Atten Hold
Attenuator hold prevents the fixed RF output attenuators from
switching in and out, eliminating the loss of the output signal as the
level is changed. This function is helpful when making squelch
measurements.
Operating Considerations
When this function is set to On, the RF output level is restricted to a
range around the present Amplitude setting. This range varies with
the amplitude setting. Attempting to set an amplitude outside the
allowed range results in an error message and beep (if the beeper is on).
RF output level accuracy is greatly degraded outside the allowed range.
