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
:TIMebase:MODE?
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?
2-50
Set the scan mode as main time base.
Return MAIN.
