Programming Guide for DS1000B Series

2-52

Function:

The command sets the timebase offset of main mode, 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.

In MAIN mode, [:MAIN] may be omitted.

Query Format:

:TIMebase:MAIN:OFFSet?

Return Format:

The query returns the value of timebase offset, and the unit is s.

Example:

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

:TIMebase:OFFSet□1 Set the timebase offset as 1s.

:TIMebase:OFFSet? Return 1.000e+00.

5. :TIMebase[:MAIN]:SCALe

Command Format:

:TIMebase[:MAIN]:SCALe□<scale_val>

Function:

The command sets the timebase scale of main mode, and the unit is s/div.

 In NoRMAL mode, different types of instruments have different sweep ranges:

DS1204B instrument，<scale_val> range：1ns/div~50s/div.

DS1104B instrument，<scale_val>range：2ns/div~50s/div.

DS1064B instrument，<scale_val>range：5ns/div~50s/div.

 In SCAN mode, <scale_val>range: 50ms ~ 50s.
