RS-232 Serial Port Data Rate (BAUD)
The Baud rate for the RS-232 serial port is configurable at 2400, 4800,
9600, 14,400, and 19,200 bps. The default setting is 9600 bps.
9600, 14,400, and 19,200 bps. The default setting is 9600 bps.
Frequency Modulation (FM)
The Counter can measure signals that are modulated in frequency, such as
a microwave radio carrier. When FM is set to AUTO (the default setting),
the Counter automatically detects FM signals and modifies its
measurement algorithm accordingly. Since this increases the time it takes
to compute each measurement, you can turn this feature OFF to increase
measurement speed, or leave it set to AUTO to increase accuracy when
measuring FM signals.

Channel 1 Low-Pass Filter (CH1 LPF)
The Counter has a built-in 50 KHz low-pass filter that can be enabled
from the Menu to eliminate measurement distortions that result from
noise in low-frequency signals. When the low-pass filter is enabled,
signals above 50 KHz cannot be measured on Channel 1.

Recall User Settings (RECALL)
Up to nine sets of settings you make for the Counter’s configurable
functions can be saved in non-volatile memory. The RECALL menu option
allows you to select and implement any of the sets you have previously
saved. The settings in set zero are automatically loaded on power-up.
The Save and Recall functions enable faster and easier operation, reduce
operator errors, and reduce training requirements.

Save User Settings (SAVE)
The SAVE menu option allows you to save the Counter’s current settings
for configurable functions in non-volatile memory for use at a later time.
Nine sets of settings can be saved. The Save and Recall functions enable

requirements.

Power Correction (PWR CORR)
Used to compensate for losses in the test configuration. See page 2-30.
