Setup

NOTE

Use MIN/MAX to track variations in a mea- surement over time, or while adjusting exter- nal devices or tuning over frequency.

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:

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	This is the sensor, combination of sensors, or rear panel BNC input
[CHCFG]	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 V, or dBmV. If the External Volts
	input is selected, the units are fixed to Volts.
RESO-	The number of decimal places in which the results are displayed in
LUTION	Readout mode, with certain limitations. If the units selected are in
[CHRES]	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	This selection turns on the Min/Max Tracking for the display chan-
[MNMXS	nel selected. On the top line of the data display, when not in menu
GMNMX]	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
	SystemGraphicsTRACKING 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.
