Command Quick Reference
FORMat
[:DATA] <format>[, <size>]
Set format for response data from [SENSe:]DATA?
ASCii[, 7]
Seven bit ASCII format (not as fast as 32-bit because of conversion)
PACKed[, 64]
Same as REAL, 64 except NaN, +INF and -INF formatted for BASIC
REAL[, 32]
IEEE 32-bit floating point (requires no conversion so is fastest)
REAL, 64
IEEE 64-bit floating point (not as fast as 32-bit because of conversion)
[:DATA]?
Returns format: REAL, +32 | REAL, +64 | PACK, +64 | ASC, +7
INITiate
[:IMMediate]
Put module in Waiting for Trigger state (ready to make one scan)
INPut
:FILTer
Control filter Signal Conditioning Plug-ons
[:LPASs]
:FREQuency <cutoff_freq>,(@<ch_list>)
Sets the cutoff frequency for active filter SCPs
:FREQuency? (@<channel>)
Returns the cutoff frequency for the channel specified
[:STATe] ON | OFF, (@<channel>)
Turn filtering OFF (pass through) or ON (filter)
[:STATe]? (@<channel>)
Return state of SCP filters
:GAIN <chan_gain>,(@<ch_list>)
Set gain for amplifier-per-channel SCP
:GAIN? (@<channel>)
Returns the channel's gain setting
:LOW <wvolt_type>,(@<ch_list>)
Controls the connection of input LO on a Strain Bridge (Opt. 21 SCP)
:LOW? (@<channel>)
Returns the LO connection for the Strain Bridge at channel
:POLarity NORmal | INVerted,(@<ch_list>)
Sets input polarity on a digital SCP channel
:POLarity? (@<channel>)
Returns digital polarity currently set for <channel>
MEASure
MEAS performs automatic setup and measurement scanning:
:VOLTage
return value in volts;
:EXCitation? (@<ch_list>)
measure excitation voltage at strain bridge, send to EU conversion
:UNSTrained? (@<ch_list>)
measure unstrained bridge output voltage, send to EU conversion
MEMory
:VME
:ADDRess <mem_address>
Specify address of VME memory card to be used as reading storage
:ADDRess?
Returns address of VME memory card
:SIZE <mem_size>
Specify number of bytes of VME memory to be used to store readings
:SIZE?
Returns number of VME memory bytes allocate to reading storage
:STATe 1 | 0 | ON | OFF
Enable or disable reading storage in VME memory at INIT
:STATe?
Returns state of VME memory, 1=enabled, 0=disabled
OUTPut
:CURRent
:AMPLitude <amplitude>,(@<ch_list>)
Set amplitude of Current Source SCP channels
:AMPLitude? (@<channel>)
Returns the setting of the Current Source SCP channel
:STATe ON | OFF,(@<ch_list>)
Enable or disable the Current Source SCP channels
:STATe? (@<channel>)
Returns the state of the Current Source SCP channel
:POLarity NORmal | INVerted,(@<ch_list>)
Sets output polarity on a digital SCP channel
:POLarity? (@<channel>)
Returns digital polarity currently set for <channel>
:SHUNt ON | OFF,(@<ch_list>)
Adds shunt resistance to leg of Bridge Completion SCP channels
:SOURce INTernal | EXTernal,(@<ch_list>)
Selects either the VT1529A/B’s internal shunt resistor or an external
shunt resistor
:SHUNt? (@<channel>)
Returns the state of the shunt resistor on Bridge Completion SCP channel
:TTLTrg
:SOURce FTRigger | LIMit | SCPlugon | TRIGger
