SCALe

Command :TIMebase:SCALe <value>

This command sets the time base scale. This corresponds to the horizontal scale value dis-

played as time/div on the analyzer screen.

<value> Value can optionally have units of bits or seconds, refer to Table 1-8 on page 1-25 to view the

suffix units. If no units are specified <value> has units of the current units setting.

seconds:time per division

bits:bits on screen at bit rate setting

Query :TIMebase:SCALe? [{BITS | TIME}]

The query returns the current scale time setting. If the optional parameter is omitted, the

scale value returned is in the units of the current units setting (bits or time).

BITS bits/screen at bit rate

TIME seconds/division

Returned Format [:TIMebase:SCALe] <time><NL>

Examples 10 OUTPUT 707;":TIMEBASE:SCALE 10E-3"

UNITs

Command :TIMebase:UNITs {TIME | BITS}

This command sets the time base units.

Query :TIMebase:UNITs?
