1. :TIMebase:MODE

Command Format:

:TIMebase:MODE□<mode>

Function:

The command sets the scan mode of horizontal timebase as MAIN (main time

base) or DELayed (delayed scan time base).

Query Format:

:TIMebase:MODE?

Return Format:

The query returns MAIN or DELAYED.

Example:

:TIMebase:MODE□MAIN Set the scan mode as main time base.

:TIMebase:MODE? Return MAIN.

2. :TIMebase:DELayed:OFFSet

Command Format:

:TIMebase:DELayed:OFFSet□<offset>

Function:

The command sets the timebase offset of delayed scan, that is the offset of the

waveform position relative to center screen.

In NORMAL mode, <offset>: 1s ~ memory capacitance;

In STOP mode, <offset>: -500s ~ +500s;

In SCAN mode,<offset>:

(-6 *MainScale + 6 DelayedScale①) ~(6 *MainScale - 6 DelayedScale)

Scale is the current horizontal scale, and the unit is s/div.

NOTE①: Delay, the time range: +/- 6*MainScale; The length of time is 12*DelayedScale;

So Delayed Offset range is:

(-6MainScale + 6*DelayedScale)~(6*MainScale-6*DelayedScale).

For example: When Main 5ms，Delay 2ms, EMS memory time is +/- 6*5=30ms,

Delay time is 6*2 = 12ms. Delay Offset range: (-30+6) ~ (30-6) ms.

Query Format:

:TIMebase:DELayed:OFFSet?
