TRIGger:A:SE
THold:CLOCk:SOUrce
This command specifies the clock source for the setup and hold triggering. You
cannot specify the same source for both clock and data.

TRIGger:A:SETHold:DATa:SOUrce
Arguments
CH1–CH4 specifies the analog channel to use as the clock source waveform.
D0–D15 specifies the digital channel to use as the clock source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
AUX specifies an external trigger using the Aux In connector located on the front
panel of the oscilloscope. (For MSO/DPO 4000B series models, MDO4000C
series models without an RF option, and 2-channel MDO3000 models only.)
Examples
TRIGGER:A:SETHOLD:CLOCK:SOURCE CH1 specifies channel 1 as the clock
source for a setup and hold trigger operation.
TRIGGER:A:SETHOLD:CLOCK:SOURCE? might return :TRIGGER:A:SETHOLD:
CLOCK:SOURCE CH4
indicating that channel 4 is the clock source for a setup and
hold trigger operation.
TRIGger:A:SETHold:CLOCk:THReshold
This command specifies the clock voltage threshold for the setup and hold trigger.

Arguments
<NR3> is a floati
ng point number that specifies the clock level, in volts.
TTL specifies a preset TTL high level of 1.4 V.
Examples
TRIGGER:A:SETHOLD:CLOCK:THRESHOLD TTL specifies the preset TTL
value
of 1.4 V as the clock threshold for the setup and hold trigger.
TRIGGER:A:SETHOLD:CLOCK:THRESHOLD? might return
:TRIGGER:A:LOGIC:SETHOLD:CLOCK:THRESHOLD 1.2000E+00
indicating that the clock threshold for the setup and hold trigger is 1.2 V.
TRIGger:A:SETHold:DATa? (Query Only)
Returns the voltage threshold and data source for the setup and hold trigger.

TRIGger:A:SETHold:DATa:SOUrce
This command specifies the data source or sources for setup and hold triggering.
You can specify any combination of sources as long as none of them are also
the clock source.
For MSO/MDO4000/B models, (and MDO3000 and MDO4000C models
with the MDO3MSO or MDO4MSO option installed), you can specify any
combination of CH1-CH4 and D0-D15 as the data sources. For MSO/DPO 4000B
series models, MDO4000C series models without an RF option, and 2-channel
MDO3000 models, you can also use Aux Input.
Data sources for DPO models may be one of CH1-CH4 or the Aux Input.

Related Commands
TRIGger:A:SETHold:CLOCk:SOUrce
Arguments
CH1–CH4 specifies an analog input channel as the data source for the setup and
hold trigger.
D0–D15 specifies a digital channel as the source. (MSO/MDO4000/B models
only as well as MDO3000 and MDO400C models with option MDO3MSO or
MDO4MSO installed.)
AUX specifies an external trigger using the Aux In connector located on the front

series models without an RF option, and 2-channel MDO3000 models only.)
Examples
TRIGGER:A:SETHOLD:DATA:SOURCE CH1 sets channel 1 as the data source
for the setup and hold trigger.
TRIGGER:A:SETHOLD:DATA:SOURCE CH1,D0,D15 specifies Ch1, D0 and D15
as three data sources for the setup/hold trigger.
TRIGGER:A:SETHOLD:DATA:SOURCE? might return
:TRIGGER:A:LOGIC:SETHOLD:DATA:SOURCE CH1,D0,D15 indicating that
channel 1, digital channel 0, and digital channel 15 are the current data sources for
the setup and hold trigger.
TRIGger:A:SETHold:DATa:THReshold
This command specifies the data voltage threshold for setup and hold trigger.

TRIGger:A:SETHold:DATa:THReshold?
Arguments
TTL specifies the preset TTL high level of 1.4 V.
<NR3> is a floating point number that specifies the setup and hold data level,
in volts.
Examples
TRIGGER:A:SETHOLD:DATA:THRESHOLD TTL specifies the preset high level of
1.4 V as the current data voltage level for the setup and hold trigger.
