STOP

[SRCSPFRQ

SRCSPPWR]

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

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

[CUR]

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

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 System|Sound|CURSOR 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

[GRYT

GRYB]

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

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

on the min and max of the previous sweep.

READOUT

[GRDATA

GRDRQ]

The supplemental data readout is displayed or removed with the

READOUT soft key. The readout provides display data depending

on the graph mode and the data hold type selected, as shown

below.
