Making Measurements
Selective Level Meter
In DMM mode, the LT51 can make selective level measurements over its full
frequency range from 200 Hz to 2.2 MHz with a BW around the centre frequency
of 25 Hz, 1.74 kHz or 3.1 kHz.
Selective measurements are made at the current centre frequency, by pressing
the
key followed by the [f3] soft-key, and then choosing the BW.
Alternatively, the desired Centre Frequency can be entered directly, in which
case the 25 Hz BW is selected by default.
The level displayed is the RMS value over the BW, at the selected centre
frequency.
To cancel the selective level mode, press the
key followed by the [f3] "BW"
soft-key, and select "WIDE"
