Command
Description
ROSc:SOUrce This command specifies the source for the time base reference oscillator. The reference
oscillator locks to this source. Depending on the command argument that you specify,
you can use an external reference or use the internal crystal oscillator as the time base
reference.
ROSc:STATE? This query returns an enumeration value that indicates the lock state of the reference
oscillator specifi ed by the
ROSc:SOUrce command.
SET? Returns a listing of oscilloscope setti ngs
SOCKETServer:ENAble
This command enables or disables the socket s erver which supports a Telnet or other
TCPIP socket connection to send commands and queries to the instrument.
SOCKETServer:PORT This command sets the TCPIP port for the socket server connection.
SOCKETServer:PROTOCol This comma nd sets the protoco l for the socket server.
TEKSecure Initializes both waveform and setup memories
TIMe
This command specifies the time displayed by the oscilloscope
TOTaluptime? Returns the total number of hours that the oscilloscope has been turned on since the
nonvolatile memory was last programmed
*TRG Performs the group execute trigger (G ET)
*TST? Tests the interface and returns the status
UNLock
Unlocks front panel
USBTMC? Returns the USBTMC information used by the USB hosts to determine the instrument
interfaces.
USBTMC:PRO DU CTID:DECimal?
This query returns the product ID number as a decimal.
USBTMC:PRODUCTID:
HEXadecimal?
This query returns the product ID number as a decimal.
USBTMC:SERIALnumber? This query returns the serial number of the oscilloscope.
USBTMC:VENDORID:DECimal?
This query returns the vendor ID number as a decimal.
USBTMC:VENDORID:HEXadecimal?
This query returns the vendor ID number as a hexadecimal value. The hexadecimal vendor
ID for Tektronix instruments is 0x699.
VERBose
This command specifies the verbose state
PictBridge Command Group
Use the commands in the PictBridge Command Group to store printer settings.

Command
Description
PICTBridge:PAPERSize Sets the output print paper size
PICTBridge:PAPERType This command specifies the paper type
PICTBridge:PRINTQual This command specifies the output print quality
USBDevice:CONFigure Enables or disables the rear USB port for use with Pictbridge printers
Power Command Group
Use the commands in the Power Command Group for power analysis. The power
measurements include:
Power quality
Switching loss
Safe operating area
Harmonics
Ripple
Modulation analysis
This command group is available when the DPO4PWR application module
is installed, except for the MDO3000 series, which requires the MDO3PWR
application module..
NOTE. To ensure that the power commands are enabled, use the command
APPLication:TYPe LIMITMask.
Table 2-36: Power Commands
Command Description
APPLication:TYPe
When a mask/limit or power test application module is installed, one of the associated test
types is always selected by default. This command allows the test type to be changed
from the default.
POWer:CURRENTSOurce This command specifi es the current source for the power application
POWer:DISplay
This command controls whether or not to display the power test results.
POWer:QUALity:VCRESTfactor? This query returns the measurement for the voltage crest factor.
POWer:GATESOurce This command specifies the gate source for the power application
POWer:GATing This command specifies the power application gating
POWer:HARMonics:DISplay:SELect This command specifies the harmonics to be displayed when the harmonics standard is None
POWer:HARMonics:DISplay:TYPe This command specifies the display type for harmonics tests
POWer:HARMonics:FREQRef This command specifies the frequency reference waveform for harmonics tests

This command specifies the line frequency for MIL-STD-1399 Section 300A harmonics tests
POWer:HARMonics:MIL:
POWERLEVel
This command specifies the power level for MIL-STD-1399 Section 300A harmonics tests
POWer:HARMonics:NR_HARMonics Sets of returns the number of harmonics (a value i n the range of 20 to 400) when the
harmonics standard is NONe
POWer:HARMonics:RESults:
HAR<1-400>:FREQuency?
Returns the frequency of the harmonic
POWer:HARMonics:RESults:
