  • Page 79 Resolution for Symptom 2 The 2003RP has a limit on how fast it can process commands sent over the bus. When developing an application program that controls the 2001RP AC source, this must be considered. Specifically, if non-query commands (commands that don‟t wait for a response such as output setup commands) are sent at too high a rate, the AC source may not be able to process them.

  • Page 82: Introduction To Scpi

    Introduction to SCPI SCPI (Standard Commands for Programmable Instruments) is a programming language for controlling instrument functions over the RS232 or IEEE 488 bus. The same SCPI commands and parameters control the same functions in different classes of instruments. For example, you would use the same MEAS:VOLT? command to measure the AC source output voltage or the output voltage of a SCPI-compatible Multimeter.

  • Page 83: Figure 9-1: Partial Command Tree

    The SCPI Command Tree As previously explained, the basic SCPI communication method involves sending one or more properly formatted commands from the SCPI command tree to the instrument as program messages. The following figure shows a portion of a subsystem command tree, from which you access the commands located along the various paths (you can see the complete tree in appendix A).

  • Page 84: Using Queries

    The message terminator after LEVel 115 returns the path to the root. Note: The 2003RP interface buffer is limited to 45 characters + [LF]. As such, compound commands should be used with care to make sure they do not exceed this message length limit.

    10.3 Measurement Subsystem This subsystem programs the measurement capability of the RP Series AC source. To select the desired phase, use the INST:NSEL command before the measurement command. Once selected, a phase selection remains in effect until the next INST:NSEL command. Subsystem Syntax :MEASure :VOLTage?
  • Page 94 MEASure:CURRent:AMPLitude:MAX? This query returns the peak value of the output AC current being sourced at the output terminals. Note that the output relay must be closed to obtain current flow. The peak current measurement circuit uses a sample and hold method and latches the highest peak current value found since the last peak measurement reset command.

    This command may be used to couple all output phases in three phase mode. For the 2003RP, this command only applies to the OUTPut:DROP command. When the phases are coupled, the OUTP:DROP command affects all three phases. This allows the output voltage to be dropped for all three phases using a single command and without the need to select each phase individually.

    10.5 Source Subsystem This subsystem programs all the output parameters of the RP Series AC source. Subsystem Syntax [SOURce:] CURRent: Set the rms current limit in amps. VOLTage: [LEVel] Set the rms output voltage value in volts. RANGe: [LEVel] Set the output voltage range. AUTO Enables or disables the AUTO range mode.
  • Page 98 [SOURce:]VOLTage This command programs the AC rms output voltage level of the power source. The maximum voltage value allowed is determined by the selected voltage range. For 2003RP- AV models configured for single voltage range, only one range is available.
  • Page 99 This command sets the voltage range of the power source. Two voltage ranges are available: a 135 volt range and a 270 volt range. However, 2003RP units with optional voltage ranges (2003RP-HV) are available as well. In this case, the actual voltage range values will be different.

  • Page 100: Output Subsystem

    To determine the actual voltage range in which the unit is operating, the VOLT:RANG? command query can be used. For 2003RP-AV models configured for single voltage range, only one range is available. In this case, the VOLT:RANGe:AUTO command has no meaning and should not be used.
  • Page 101 OUTPut:DROP The output drop command may be used to interrupt the voltage to the UUT without opening the output relay. This method uses an electronic means of interrupting the AC source output which enables short interruptions of as little as 1 ms or as long as 4000 s. In addition to short interruption times, the drop command can be set to use any of four start phase angles at which to execute the voltage drop.
  • Page 102 Example: Individual Phase Loss Test The following command sequence will drop the output of phase A only for 10 cycles at 400 /* Set up sequence VOLT 115;FREQ 400 Set output voltage to 115 V at 400 Hz (all phases) INST:COUP 0 Uncouple output phases INST:NSEL 1...
  • Page 103 OUTPut: STARt[:STATe] The output start state command is used to enable or disable the start phase logic of the AC source controller. If disabled (State = 0), any voltage drops with the OUTP:DROP command or voltage changes with the VOLT command are executed immediately without regard for the phase angle of the output sinewave.

  • Page 104: Limit Subsystem

    <NR2> LIMit:FREQuency:LOW? This command queries the lower frequency limit of the power source. On the 2003RP-AV, the frequency range may have been factory configured to a fixed single value. In this case, the High and Low frequency limits will be set to the same value and both queries will return the same number.

  • Page 105: Display Subsystem

    If the voltage limit value is less than 201 volt, the 2003RP is configured for single voltage range operation. If a value above 200 volt is returned, the 2003RP has a high and a low voltage range. On dual range configurations, the maximum voltage in the high range is returned and this value must be even.

  • Page 118: Status Registers

    12 Status Registers You can use status register programming to determine the operating condition of the AC source at any time. For example, you may program the AC source to generate an MSS bit when an event such as a current limit occurs. When the MSS bit is set, your program can then act on the event in the appropriate fashion.

  • Page 119: Standard Event Status Group

    12.2 Standard Event Status Group This group consists of an Event register and an Enable register that are programmed by Common commands. The Standard Event register latches events relating to interface communication status. It is a read-only register that is cleared when read. The Standard Event Enable register functions similarly to the enable registers of the Operation and Questionable status groups.

  • Page 120: Examples

    12.4 Examples The following section contains examples of commonly used operations involving the status registers. You can determine the reason for an MSS bit set by the following actions: Step 1 : Determine which summary bits are active. Use: *STB? Step 2 : Read the corresponding Event register for each summary bit to determine which events caused the summary bit to be set.
