4-4 SENSOR MENU
Setup
NOTE
The MODE selection is not available in Profile or Source Sweep modes.
NOTE
When measuring mod- ulated signals with a di- ode sensor, ensure Modulated Average is selected or measure- ment errors may result.
The Sensor menu has controls for sensor data processing.
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.
Selects the data acquisition controls for the sensor. The following submenus are displayed.
SENSOR Model ML2438A (dual channel) only. Select the sensor to be con- figured. Toggles between Channel A and Channel B for all sub- menu functions.
OPTION Only displayed if a Universal Power Sensor with Option 01 is con- nected 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. [SENMM]
Default is the sensor mode setting following system preset. It is the ML2430A Series simplest operating mode. Measurement speed is automatically adjusted according to sensor response times and the
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 ML2430A Series receipt of a valid trigger event and the start of sample integration) and Gate Width (the du- ration of sample integration) controls are located in the Trigger menus.
When using universal power sensors only default mode is avail- able unless OPTION is set to Fast CW. Fast CW can only be se- lected for sensors supplied with option 01.
