Anritsu ML2437A - Sensor Menu

Front Panel Operation Sensor Menu
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 5-5
5-3 Sensor Menu
The Sensor menu has controls for sensor data processing.
Setup
Selects the data acquisition controls for the sensor. The following submenus are displayed.
SENSOR
Model ML2438A (dual channel) only. Select the sensor to be configured. Toggles
between Channel A and Channel B for all submenu functions.
OPTION
Only displayed if a Universal Power Sensor with Option 01 is connected to selected
input channel. This key selects between True RMS sensor operation (for WCDMA
measurements) and Fast CW (for TDMA/Pulse measurements).
MODE
Select either Default, Modulated Average, or Custom.
Default is the sensor mode setting following system preset. It is the ML243xA simplest
operating mode. Measurement speed is automatically adjusted according to sensor
response times and the user-adjustable Settling %. Triggering controls, except for GPIB
trigger, are disabled when the sensor mode is set to Default. This is intended to
simplify basic power measurement by avoiding the necessity of specific trigger settings.
Modulated Average mode is used to stabilize the front panel digital readout. It is a
specialized sensor mode for either MA2440A or MA2470A Series power sensors. These
sensors are fast enough to demodulate the amplitude modulation of many RF test
signals. The Mod Average sensor mode is unnecessary for thermal power sensors.
The Custom sensor mode permits the highest measurement rates. Trigger controls are
available with this sensor mode. Trigger Delay (the time between the ML243xA receipt
of a valid trigger event and the start of sample integration) and Gate Width (the
duration of sample integration) controls are located in the Trigger menus.
When using universal power sensors only default mode is a available unless OPTION is
set to Fast CW. Fast CW can only be selected for sensors supplied with option 01.
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.
Note The MODE selection is not available in Profile or Source Sweep modes.
Note
When measuring modulated signals with a diode sensor, ensure Modulated
Average is selected or measurement errors may result.
