Syntax
AUXin:PRObe:RESistance?
Examples
AUXin:PRObe:RESistance? might return :AUXin:PROBE:RESISTANCE
1.0000E+6
indicat
ing that the input resistance of the probe attached to the front
panel Aux In connector is 1 MΩ.
NOTE. This query will return 0.0 if no probe is attached or the attached probe
does not report the input resistance.
AUXin:PRObe:SIGnal
This command ch
anges the input bypass setting on VPI probes that support input
bypass, for example the TCP0001. If sent to a probe that does not support input
bypass, it is ignored.
Conditions
Available for MSO/DPO4000B series models, 2-channel MDO3000 models, and
MDO4000C models without option SA3 or SA6 only.

nal?
Arguments
ByPass sets the probe to Bypass mode.
PASS sets the probe to Pass mode.
AUXin:PRObe:UNIts? (Query Only)
Returns a string describing the units of measure of the probe attached to theAux
Input connector.
Conditions
Available for MSO/DPO4000B series models, 2-channel MDO3000 models, and
MDO4000C models without option SA3 or SA6 only.

AUXOut:SOUrce
This command sets (or queries) the source for the Auxiliary Output port.

Syntax
AUXOut:SOUrce {ATRIGge r|MAIn|REFOut|EVENT|AFG}
AUXOut:SOUrce?
Arguments
ATRIGger is the default signal output of the auxiliary out port. MAIn is
synonymous with
ATRIGger.
REFOut specifies the reference oscillator output as the source for the auxiliary
output. (Not supported on MDO3000 models.)
EVENT refers to an internally generated oscilloscope event. The Mask and Act
on Event commands can cause an event output, such as a mask test completion
notification event.
AFG specifies the AFG sync out pulse. (Only available for MDO3000 and
MDO4000C models with the MDO3AFG or MDO4AFG option installed.)
Examples
AUXOut:SOUrce REFOut sets the instrument to use the reference oscillator
output as the source for the auxiliary output.
AUXOut:SOUrce? might return ATRIGGER, indicating the source for the
auxilliary out port is the A Trigger.
BUS? (Query Only)
Returns the parameters for each serial (if installed) and parallel bus.

Syntax
BUS?
BUS:B<x>:ARINC429A:BITRate
This command specifies the bit rate for the ARINC429 bus.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.
Group
Bus
Syntax
BUS:B<x>:ARINC429A:BITRate {LOW|HI|<NR1>}
BUS:B<x>:ARINC429A:BITRate?
Arguments
LOW sets the ARINC429 bit rate to handle low speed signals (12000
bits-per-second to 14500 bits-per-second).
HI sets the ARINC429 bit rate to handle high speed signals (100,000
bits-per-second)
<NR1> is a bit rate in bits-per-second. You can enter any positive integer, and the
instrument will coerce the value to the closest supported bit rate.
BUS:B<x>:ARINC429A:DATA:FORMAT
Specifies the format of the DATA field in ARINC429 packets on a bus.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.
Group
Bus
Syntax
BUS:B<x>:ARINC429A:DATA:FORMAT {DATA|SDIDATA|SDIDATASSM}
BUS:B<x>:ARINC429A:DATA:FORMAT?
Arguments
DATA sets the ARINC429 DATA field width to 19 bits wide (covering bits 11
through 29 of the 32 bit packet)
SDIDATA sets the ARINC429 DATA field width to 21 bits wide (covering bits 9
through 29 of the 32 bit packet)
