FRQSTART (Frequency Start)

Command Type:

Setting or query

Setting Syntax:

FRQSTART < freq > [: < units > ]

Examples:

FRQSTART 59.99

FRQSTART 9.99:MHZ

Query Syntax:

FRQSTART?

Query Response:

FRQSTART < freq >

;

FRQSTART 1.0E + 6

;

Discussion:

T his command sets the frequency at which a sweep

will begin. Start frequency must be greater than stop

frequency. Resolution is 4 digits; default unit of meas

ure is Hz.
T he power-on setting is FRQSTART 1 Hz.

Units of measure can be Hz, kHz, or MHz.
FRQSTART and F RQSTOP are not checked for illegal

setting and are not updated until SWEEP ON is sent.
