Power Meter Remote Operation Zeroing and Calibrating the Power Meter Setting the Reference Calibration Factor All the HP 8480 series power sensors require you to set the reference calibration factor. The reference calibration factor can be set by: • entering the value into the power meter using the CALibrate[1|2]:RCFactor command.
You can select the measurement’s expected power level, resolution and with the HP E4419B the measurement type (that is single channel, difference or ratio measurements) all in one command. The power meter automatically presets other measurement parameters to default values as shown in Table 1-3.
You cannot change any settings (other than the expected power value, resolution and with the HP E4419B the measurement type) before the measurement is taken. This means you cannot fine tune the measurement, for example, you cannot change the filter length.

The operation of the MEAS1? command when the source list parameter is defaulted is described in the note on page 1-18. Note For the HP E4418B it is not necessary to specify a channel as only one channel is available.

Power Meter Measurement Actions Idle State Turning power on, sending an HP-IB CLEAR, sending a *RST or an :ABORt forces the trigger system into the idle state. The trigger system remains in the IDLE state until it is initiated by INITiate:CONTinuous ON or INITiate:IMMediate.
TRIGger:SOURce There are three possible trigger sources. • The trigger source is the HP-IB group execute trigger (<GET>), a *TRG command, or the TRIGger:IMMediate command. • HOLD Triggering is suspended. The only way to trigger the power meter is to send TRIGger:IMMediate.
To disable the delay, use the following command: TRIGger:DELay:AUTO OFF Note MEASure? and CONFigure automatically enable the delay.

The SRQ Method When a bit of the Status Register is set and has been enabled to assert SRQ (*SRE command), the power meter sets the HP-IB SRQ line true. This interrupt can be used to interrupt your program to suspend its current operation and find out what service the power meter requires.

This chapter contains information about the IEEE 488.2 Common (*) Commands that the power meter supports. It also describes the universal command statements which form the nucleus of HP-IB programming; they are understood by all instruments in the network. When combined with programming language codes, they provide all management and data communication instructions for the system.
IEEE488.2 Command Reference Universal Commands Universal Commands The DCL (Device Clear) command causes all HP-IB instruments, or addressed instruments, to assume a cleared condition. The definition of device clear is unique for each instrument. For the power meter: • All pending operations are halted, that is, *OPC? and *WAI.
Once the power meter has received a PPC command, the PPE (Parallel Poll Enable) secondary command configures the power meter to respond to a parallel poll on a particular data line with a particular level. 15-4 HP E4418B/E4419B Programming Guide...
The PPU (Parallel Poll Unconfigure) command disables the power meter from responding to a parallel poll. This is effectively a universal disable. The SDC (Selected Device Clear) command causes all HP-IB instruments in the listen state, to assume a cleared condition. The definition of a selected device clear is unique for each instrument.
The SPE (Serial Poll Enable) command establishes the serial poll mode for the power meter. When the power meter is addressed to talk, a single eight bit status byte is returned (refer to “The Status Byte”, on page 1-80 for further information). 15-6 HP E4418B/E4419B Programming Guide...
The *CLS (CLear Status) command clears the status data structures. The SCPI registers (Questionable Status, Operation Status and all the other SCPI registers), the Standard Event Status Register, the Status Byte, and the Error/Event Queue are all cleared. Syntax *CLS HP E4418B/E4419B Programming Guide 15-7...
Examples of <arbitrary block program data> parameters are: • #15FETC? and #206FETCh? Examples of <string program data> are: • "FETCh1?", "FETCh?" and "TRIG1;FETC1" Reset Condition On reset, the <action> field of *DDT is set to *TRG. 15-8 HP E4418B/E4419B Programming Guide...
