Command
Description
CALibration (cont.)
:TARE (@<ch_list>) Calibrate out system field wiring offsets
:RESet Resets cal constants from CAL:TARE back to zero for all channels
:TARE? Returns state of CAL:TARE operation (returns error codes or 0 for OK)
:VALue
:RESistance <ref_ohms> Send to instrument the value of just measured reference resistor
:VOLTage <ref_volts> Send to instrument the value of just measured voltage reference
:ZERO? Correct A/D for short term offset drift (returns error codes or 0 for OK)
DIAGnostic
:CALibration
:SETup
[:MODE] 0 | 1 Set analog DAC output SCP calibration mode
[:MODE]? Return current setting of DAC calibration mode
:TARe
[:OTD]
[:MODE] 0 | 1 Set mode to control OTD current during tare calibration
[:MODE]? Return current setting of OTD control during tare calibration
:CHECksum? Perform checksum on Flash RAM and return a ‘1’ for OK, a ‘0’ for
corrupted or deleted memory contents
:COMMand
:SCPWRITE <reg_addr>,<reg_data> Writes values to SCP registers
:CUSTom
:LINear <table_ad_range>,<table_block>,(@<ch_list>) Loads linear custom EU table
:PIECewise <table_ad_range>,<table_block>,(@<ch_list>) Loads piecewise custom EU table
:REFerence:TEMPerature Puts the contents of the Reference Temperature Register into the FIFO
:INTerrupt[:LINe] <intr_line> Sets the VXIbus interrupt line the module will use
:INTerrupt[:LINe]? Returns the VXIbus interrupt line the module is using
:OTDetect[:STATe] ON | OFF, (@<ch_list>) Controls “Open Transducer Detect” on SCPs contained in <ch_list>
:OTDetect[:STATe]? (@<channel>) Returns current state of OTD on SCP containing <channel>
:QUERy
:SCPREAD? <reg_addr> Returns value from an SCP register
:VERSion? Returns manufacturer, model, serial#, flash revision # and date
e.g. AGILENT TECHNOLOGIES,E1419B,US34000478,A.04.00, Wed Jul
08 11:06:22 MDT 1994
FETCh? Return readings stored in VME Memory (format set by FORM cmd)
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 format compatible with
Agilent 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
Put module in Waiting for Trigger state (ready to make one scan)
INPut
:FILTer Control filter Signal Conditioning Plug-Ons
[:LPASs] Sets the cutoff frequency for active filter SCPs
:FREQuency <cutoff_freq>,(@<ch_list>) Returns the cutoff frequency for the channel specified (@<channel>)
:FREQuency? (@<channel>)
[:STATe] ON | OFF Sets the state of the SCP filters
[: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)
