STOP Sweep stop frequency (MHz or GHz) or power (dBm)

[SRCSPFRQ

NOTE

When the power meter is communicating with a signal source/generator over the serial interface, if the source fre- quency power level or the frequency itself is changed, the source sweep display will be updated where appropriate.

Control The Control menu adjusts cursor position and toggles the readout display in Pro- file, Power vs. Time and Source Sweep modes, and provides control over display scaling.

SWAP

SWAP selects which cursor to move. The presently selected cursor

<<is defined by a triangular marker at the top of the cursor line. Press

>>the << soft key to move the selected cursor left, and the >> soft key

[CUR]

to move the selected cursor right. Trigger delay and Gate Width are

 

 

related to the cursor positions. This feature aids in measurement of

 

pulsed signals. Changing either cursor, or adjusting the Gate width

 

value, updates both the cursors and the gate width value.

 

When enabled through the SystemSoundCURSOR menu selec-

 

tion, if a cursor is moved into an illegal space such as the edge of

 

the screen or the end of valid data (trigger point on the left of the

 

screen) a warning beep will sound.

SCALE

Adjust the Y-axis of the graph using TOP dB Value and BOTTOM

[GRYT

dB Value parameters in the SCALE submenu. AUTO scale is based

on the min and max of the previous sweep.

READOUT

[GRDATA

READOUT soft key. The readout provides display data depending
