This section describes the requirements for calibrating/verification of Marvin Test Solutions GTX2200 High Resolution Universal Time Interval Counter PXI 3U card.
Supported Devices: GTX2210, GTX2220, GTX2230.
Program: GX2200.
Recommended Calibration Interval: 1 Year.
Required Hardware:
1. GTX22010, GTX22020, or GTX22030.
2. Voltage reference providing ±6.0V DC, 1mV resolution and 2mV accuracy.
3. 10MHz Frequency Standard. Reference signal should be 10MHz ±0.01PPM sine wave with amplitude of 1±0.3 Vrms into 50 ohms and less than -35dB total harmonics distortions.
4. BNC to Banana Plug, see “Calibration Harness Connections” section below for more details.
Required Software:
1. ATEasy run-time (see the ReadMe.txt for supported versions).
2. GxCnt v3.4 or newer.
3. CalEasy v1.4.7 or newer.
4. Standards manufacturer's driver software as specified below.
Required Standards and Capabilities:
1. REF – Voltage reference providing
±6.0V DC, 1mV resolution and 2mV accuracy.
Provided instrument driver: Keithley2400 Source Meter SMU (recommended
instrument), Fluke 5522A/5500A, Fluke 57xxA, Marvin Test Solutions GX1648,
Marvin Test Solutions GX1649.
Note: See Instrument Standards DLL Files section for more information about the Standards Driver software requirements and setup.
2. FREQREF – 10MHz Frequency Standard. Reference signal should be 10MHz ±0.01PPM sine wave with amplitude of 1±0.3 Vrms into 50 ohms and less than -35dB total harmonics distortions.
Provided instrument driver: CalFreqRef – This driver that is provided with CalEasy and is used as a placeholder for the use to input the Frequency standard Manufacturer, Model, Serial, and calibration information to the calibration/verification logs and the calibration certification. CalEasy does not configure, set or control any instrument used when this driver is used. It is the user responsibility to configure the Frequency standard output to match or accede the requirements when the calibration program promote the user to do so. Recommended instrument: Stanford Research Systems FS725 - Rubidium Frequency.
The following diagram shows the connections of the GTX2200 board to a DC Voltage Reverence, which has a double banana input.
Connections to a DC Voltage Reverence with Double Banana Input
The following diagram shows the connections of the GTX2200 board to a DC Voltage Reverence, which the user provides the connections.
Connections to a DC Voltage Reverence when User Provides the Connections
1. Connect the GTX2200 channel A to the BNC connector.
2. Connect the BNC cable that is connected to a Double Stacking Banana Plug Adapter.
3. In case the Voltage reference output type is a banana, connect using a BNC cable to Double Stacking Banana Plug Adapter. Otherwise, the user needs to provide a connection between the BNC connector and the Voltage reference.
The following diagram shows the connections to calibrate the GTX2200 board using a Frequency Standard.
If the 10MHz Frequency standard output is a BNC connector, then using a BNC cable, connect the GTX2200 input channel A or B to the 10MHz Frequency standard. Otherwise, the user needs to provide a connection between the GTX2200 BNC input channel A or B to the 10MHz Frequency standard.
Calibrate the GTX2200 Board using a Frequency Standard
1. Start CalEasy.exe executable.
2. Select standards instruments for DMM.
3. Select standards instruments for REF.
4. Click Start.
5. Select the verification and calibration program mode: Verify, Verify and if Passed, Update Calibration Date, Verify and Calibrate If Required or Calibrate.
6. Run Calibration Program.
7. When prompted, connect the DMM or the REF as instructed by the pop-up boxes.
Verification – About 4 minutes.
Calibration – About 8 minutes.
