    WARNINGS The HP E1563A and E1564A Digitizers are capable of measuring voltages up to 256V maximum. Voltage levels above the levels specified for accessible connectors or cable ends could cause bodily injury or death to an operator. Special precautions must be adhered to (discussed below) when applying voltages in excess of 60 Vdc, 30 Vac rms or 42.4 Vac peak for a continuous, complex waveform.

  • Page 9: Digitizer Module Set-Up

    • Initial Operation General Information The HP E1563A (2-channel) and HP E1564A (4-channel) are 800 kSample/second (14-bit resolution) digitizers capable of handling both continuous and transient voltages up to 256V. They are ideal for measurements in electomechanical design characterization, particularily in environments with high levels of electrical noise.
  • Page 10 Module Differences channel (1.5 kHz, 6 kHz, 25 kHz and 100 kHz) that can be enabled. • The E1563A 2-Channel Digitizer has a fixed 25 kHz input filter per channel that can be enabled. • The E1564A 4-Channel Digitizer has a calibration bus output (High, Low and Guard) and a programmable short.
  • Page 11 WARNING voltages. Making cables and connectors that carry hazardous voltages inaccessible is a protective measure keeping an operator from inadvertent or unknowing contact with these harmful voltages. Cables and connectors are considered inaccessible if a tool (e.g., screwdriver, wrench, socket, etc.) or a key (equipment in a locked cabinet) is required to gain access to them.

    Installing the Digitizer in a Mainframe The HP E1563A or E1564A can be installed in any slot (except slot 0) in a C-size VXIbus mainframe. Refer to following diagram for the procedure to install the Digitizer in a mainframe. 1. Set the extraction levers out.

  • Page 18 3-Wire and 2-Wire The HP E1563A and E1564A Digitizers provide a three-terminal input system (High, Low and Guard). An unavoidable and undesirable current is Input Cabling injected from chassis ground to the Guard terminal. Dependent on whether Considerations you measure on a low-voltage range or a high-voltage range, the way you connect the Guard terminal may or may not introduce a measurement error due to this current.
  • Page 19 3-Wire Cable Connection Example 2 Two-Wire Connection When Low and Guard are simply connected together at the digitizer’s input on a low-voltage range (4V and below), the injected current is directed to flow through the source impedance (in a floating source) and the resultant voltage drop will introduce a measurement error.

  • Page 29: Triggering The Digitizer

    Triggering the Digitizer Two Common Triggering digitizer readings across all input channels is accomplished with one or both of the two available trigger sources (TRIGger:SOURce1 and Trigger Sources per TRIGger:SOURce2). The trigger event can be different for each source e.g., Channel SOURce1 can be EXT and SOURce2 can be TTLT0.

    Digitizer Command Reference Using This Chapter This chapter describes the Standard Commands for Programmable Instruments (SCPI) and IEEE 488.2 Common (*) commands applicable to the HP E1563A and HP E1564A Digitizers. Command Commands are separated into two types: IEEE 488.2 Common Commands and SCPI Commands.
  • Page 40 (CALCulate:LIMit) and the second level from the third level (LIMit:FAIL?). Abbreviated The command syntax shows most commands as a mixture of upper and lower case letters. The upper case letters indicate the abbreviated spelling for the command. Commands For shorter program lines, send the abbreviated form. For better program readability, you may send the entire command.

A “0” is returned if the limit was not exceeded.

  • Page 47: Calibration

    CALibration:SOURce is set to INTernal. The voltage specified is output by the internal DAC to the calibration bus (HP E1564A 4-Channel Digitizer only). You can measure this voltage on the top two pins of the front panel D-sub connector (CAL-H and CAL-L) and is used for calibrating the digitizer’s gain as the CAL:VALue.
  • Page 48 :DAC:VOLTage? CALibration:DAC:VOLTage? MIN | MAX queries the setting of the calibration DAC (HP E1564A 4-Channel Digitizer only). The DAC voltage is output to the calibration bus and accessible at the front panel D-connector only if the CALibration:SOURce is set to INTernal. The MIN parameter returns the minimum voltage available from the DAC and MAX returns the maximum voltage available from the DAC.
  • Page 49 CALibration:SOURce EXTernal is used. You must enter the external calibrator voltage value with the CAL:VALue command when an external calibration source is used. The HP E1564A 4-Channel Digitizer automatically applies the DAC voltage to the internal calibration bus when CALibration:SOURce INTernal is used. You must measure the DAC voltage at the front panel pins (for CAL:SOURce INTernal) and enter that value with the CAL:VALue command.
  • Page 50 “EXTernal” is the default source, a voltage must be provided from an external source to the channel being calibrated. Note The “INTernal” source is available only on the HP E1564A 4-Channel Digitizer. CAL:SOURce INTernal outputs the specified DAC voltage set by CAL:DAC:VOLT <...
  • Page 51 This value informs the digitizer what voltage is either being placed on the front panel input connector (CAL:SOURce EXTernal) or the value being generated by the internal DAC (HP E1564A 4-Channel Digitizer only) and Digitizer Command Reference...
  • Page 52 DAC is 15V. See the following paragraphs. HP E1564A 4-Channel Digitizer Internal DAC The internal DAC on the HP E1564A can be used for the calibration source when CAL:SOURce INTernal is specified. The output level of this DAC is specified with the CAL:DAC:VOLTage command.
  • Page 53 :VALue? CALibration:VALue? queries the present setting of the calibration voltage. :ZERO CALibration:ZERO[<channel>] [<samples>][,<rate>] initiates an offset calibration for the current range on the specified channel using an internal short.

  • Page 54 :ZERO:ALL? CALibration:ZERO[<channel>]:ALL? [<samples>][,<rate>] initiates a zero offset calibration for all ranges on the specified channel using an internal short. The command returns “0” if the calibration was successful. It returns a non-zero value if an error occurred while calibrating one of the ranges. The non-zero return value contains the failed ranges as high bits in the lower word.

  • Page 64: Initiate

    INITiate The INITiate subsystem controls the initiation of the trigger system and prepares the Digitizer to take voltage measurements. Once a trigger is received from the programmed source (TRIGger:SOURce command), measurements begin on all channels. Normally, all measurement setup (setting measurement ranges, sample count and trigger sources, etc.) should be done before this command is sent.
  • Page 65 3. The instrument’s FIFO memory is filled. This can be prevented by fetching the data from memory in blocks faster than the sample rate can fill memory. Note The INIT[:IMMediate] and INIT:CONTinuous commands return “1” to *OPC? when the instrument begins measurement not when measurements complete. To determine when a non-continuous measurement is complete, use the DIAG:STATus? command and monitor bit 6.

    Calibration Interval The HP E1563A and HP E1564A digitizer should be calibrated on a regular interval determined by the measurement accuracy requirements of your application. A 90 day interval is recommended for the most demanding applications, while a 1 year or 2 year interval may be adequate for less demanding applications.

  • Page 158: Adjustment Procedures

    Whatever calibration interval you select, HP recommends that complete re-adjustment should always be performed at the calibration interval. This will increase your confidence that the HP E1563A or HP E1564A will remain in specification for the next calibration interval. This criteria for readjustment provides the best measure of the digitizer’s long-term stability.

  • Page 161 Adjustment performed one time followed by the other gain adjustments. The HP E1564A 4-Channel Digitizer has an internal DAC that outputs to a calibration bus on the front panel D-connector. This procedure uses the calibration bus and does not require an external DC Standard.
