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? might return
:TRIGGER:A:SETHOLD:DATA:SOURCE CH2;THRESHOLD 80.0000E-3
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
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: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.
Group
Trigger
Syntax
TRIGger:A:SETHold:DATa:THReshold {<NR3>|TTL}
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.

Syntax
TRIGger:A:SETHold:HOLDTime <NR3>
TRIGger:A:SETHold:HOLDTime?
Arguments
<NR3> is a floating point number that specifies the hold time setting, in seconds.
Positive values for hold time occur after the clock edge. Negative values oc
cur
before the clock edge.
Examples
TRIGGER:A:SETHOLD:HOLDTIME 3.0E-3 sets the hold time for the setup and
hold trigger to 3 ms.
TRIGGER:A:SETHOLD:HOLDTIME? might return
:TRIGGER:A:SETHOLD:HOLDTIME 2.0000E-09 indicating that the current
hold time for the setup and hold trigger is 2 ns.
TRIGger:A:SETHold:SETTime
This command specifies the setup time for setup and hold violation triggering.

Arguments
<NR3> is a floating point number that specifies the setup time for setup and hold
viol
ation triggering.
Examples
TRIGGER:A:SETHOLD:SETTIME 3.0E-6 specifies that the current setup time for
setup and hold trigger is 3 µs.
