5-4 Channel Menu
The Channel menu controls the operation of a display channel. There are two display
channels, Channel 1 and Channel 2. Channel 1 appears at the top of the readout display and
channel 2 at the bottom. If a channel input configuration is turned off, the remaining channel
appears in the centre of the screen.
The Channel submenus are as follows:
Setup
The setup menu allows the user to set up the configuration of the display channels. The setup
parameters are:
CHANNEL
Selects the channel to be configured. Toggles between Channel 1 and Channel 2.
INPUT [CHCFG]
This is the sensor, combination of sensors, or rear panel BNC input that is used to
calculate the measured and processed value for this channel. For the ML2437A (single
input) power meter, the available options are A, External Volts, or OFF. For the
ML2438A (dual input) power meter, the options are A, B,
A – B, B – A, A/B, B/A, External Volts, or OFF.
UNITS [CHUNIT]
The units can be dB(m), Watts, dBV, or dBmV. If the External Volts input is selected,
the units are fixed to Volts.
RESOLUTION [CHRES]
The number of decimal places in which the results are displayed in Readout mode, with
certain limitations. If the units selected are in Watts or Volts, and the value goes down
to pW or V, the number of decimal places is forced to zero. If the number to be displayed
is too large for the number of decimal places selected, the decimal places displayed will
be reduced.
MIN/MAX [MNMXS GMNMX]
This selection turns on the Min/Max Tracking for the display channel selected. On the
top line of the data display, when not in menu mode, the min and max of the channel
data (after combination and unit conversion calculations) is displayed. The left hand set
of data is for display channel 1 and the right hand set for display channel 2.

When editing an entry in a menu, pressing the CLR key clears the digits. If in a
