GX5055 Calibration

This section describes the requirements for calibrating Marvin Test Solutions’ GX5055 Dynamically Controlled, High Voltage Digital I/O PXI Card with Pin Electronics cards using CalEasy.

Overview

Supported Devices: GX5055.

Program: GX5055.

Recommended Calibration Interval: 1 Year.

Required Hardware:

1.      GX5055.

2.      GX6377 – Switch Matrix.

3.      GX5055-5960-CALKIT: The GX5055-5960-CALKIT includes the GX95962 calibration harness assembly, a GT95032-12, 12 inch shielded SCSI cable assembly, the GT95015 interface board and a GX95963 external power cable (for externally powering the GX5960 with a GX7400 power supply).

Note: GX95963 – GX5055 Power Cable. Required only when calibrating the module using a standalone power supply (GX7400 or other), do not use if calibrating the module in a GX70x5/GX7017 chassis. The cable connects the GX5055 to a VCC and VEE power supply source and is wired for direct connection to Marvin Test Solutions’ GX7400 PXI power supply module.

Required Software:

1.      ATEasy run-time (see the ReadMe.txt for supported versions).

2.      GtDio v5.1 build 70 or newer.

3.      CalEasy v1.4.6 or newer.

4.      Standards driver manufacturer's software as specified below.

Required Standards and Capabilities:

1.      DMM  – 6 ½ digit DMM with VDC and IDC measurement functions.
Provided instrument drivers: Agilent 3458, Keithley 200x (2001, 2002), Marvin Test Solutions GX2065, Signametrics SMX204x (SM2040, SM2042, SM2044) or SM206x.

2.      SWITCH MATRIX – Switch matrix with at least 32x2 rows/columns, channel must support pin-out of the GX95962 Calibration Harness.
Provided instruments drivers: Marvin Test Solutions GX6377.

3.      PS – Power Supply with two independently controlled rails that can supply +16V/-16V and +18V/-14V. Each rail must be able to supply a maximum of 4A of current.
Provided instruments drivers: Marvin Test Solutions GX70x5 (GX7005, GX7015), GX7017, Marvin Test Solutions GX7400.

Note: The GX7400 power supply is not required if the GX5055 is installed in a GX70x5/GX7017 chassis.

Note: See Instrument Standards DLL Files section for more information about the Standard Driver software requirements and setup.

Calibration Harness Connections

In order to calibrate the GX5055 the following cables are required:

Part number
Description
GX95962
GX5055 Calibration Harness. The harness connects the GX5055 I/O connector (J6) to the switch matrix and the DMM using the 68-Pin SCSI shielded cable that is supplied with the GX5055-5960-CALKIT. The 68-Pin SCSI shielded cable can be any of the following:
GT95021 2' shielded cable.
GT95022 3' shielded cable.
GT95032 6" shielded cable.
GT95032-12 shielded cable (supplied with CALKIT).
GX95963
GX5055 Power Cable. The cable is used if the GX5055 board is not installed in the Marvin Test Solutions’ high-power GX70x5/GX70x7 chassis.

 

The following diagram shows the calibration harness connections to calibrate the Gx5055 board.

Connection Instructions when using a switch matrix

1.      Connect one side of the 68-Pin SCSI shielded cable to the GX5055 J6 I/O connector and the other side to the GT95015 (Connector Interface board). 

2.      Connect GX95962 P6 to the Switch Matrix.

3.      Connect GX95962 P1 to the DMM (for voltage measurement).

4.      Connect GX95962 P2 to the J2 connector on the GT95015 board.

Power supply connections (if not using Marvin Test Solutions’ high-power GX70x5/GX70x7 chassis):

1.      Connect GX95963 P7A or P7B to GX5055 J7 connector.

2.      Connect GX95963 P5A to Gx7400 Ch1 Out.

3.      Connect GX95963 P5B to Gx7400 Ch2 Out.

Calibration Procedure when using a switch matrix

1.      Start CalEasy.exe executable.

2.      Select standards instruments for DMM and Matrix.

3.      Click Start.

4.      Select the verification and calibration program mode: Verify, Verify and if Passed, Update Calibration Date, Verify and Calibrate If Required or Calibrate.
