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 center of the screen.
NOTE
When editing an entry in a menu, pressing the
CLR key
clears the digits. If in a menu screen, pressing the CLR key
returns to the previous menu level.
The Channel submenus are as follows:
Setup The setup menu allows the user to set up the configuration of the display chan-
nels. 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 Model 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, dB µV, or dBmV. If the External Volts
input is selected, the units are fixed to Volts.
RESO-
LUTION
[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
µV, 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 chan-
nel 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.
In Profile mode, the Min/Max is between cursors only, as controlled
by selecting
SINGLE or INFINITE through the
System|Graphics|TRACKING menu. SINGLE (default) is the most
useful as it provides a continuously updated readout of the Min/
Max points within the cursor window. The
INFINITE setting is used
when the results needs to be collated over a large number of
samples.
