Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-5164 meets
published specifications:
• Allow a warm-up time of at least 15 minutes after the chassis is powered on. The warm-
up time ensures that the PXIe-5164 is at a stable operating temperature.
• Allow all test instruments a warm-up time of at least the stated amount of time in their
specification document. The warm-up time ensures that the test instruments are at a stable
operating temperature.
• Keep cabling as short as possible. Long cables act as antennas, picking up extra noise that
can affect measurements.
• Verify that all connections to the PXIe-5164, including front panel connections and
screws, are secure.
• Use shielded copper wire for all cable connections to the module. Use twisted-pair wire
to eliminate noise and thermal offsets.
• Maintain an ambient temperature of 23 °C ± 3 °C.
• Keep relative humidity between 10% and 90%, noncondensing.
• Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters, if present, are
clean, and that the empty slots contain filler panels. For more information about cooling,
refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/
manuals.
• Plug the chassis and the instrument standard into the same power strip to avoid ground
loops.

As-Found and As-Left Limits
The as-found limits are the published specifications for the PXIe-5164. NI uses these limits to
determine whether the PXIe-5164 meets the specifications when it is received for calibration.
Use the as-found limits during initial verification.
The as-left calibration limits are equal to the published NI specifications for the PXIe-5164,
less guard bands for measurement uncertainty, temperature drift, and drift over time. NI uses
these limits to reduce the probability that the instrument will be outside the published
PXIe-5164 Calibration Procedure | © National Instruments Corporation | 9
specification limits at the end of the calibration cycle. Use the as-left limits when performing
verification after adjustment.
Calibration Overview
Install the device and configure it in NI Measurement & Automation Explorer (MAX) before
calibrating.
Calibration includes the following steps:
1. Self-calibration—Adjust the self-calibration constants of the device.
2. Test system characterization—Characterize the amplitude balance of the output ports on
your power splitter and amplitude loss through your power splitter.
The results of this step are used as a correction in the following procedures:
•Verifying 50 Ω Passband Amplitude Flatness and Bandwidth
•Verifying 1 MΩ Passband Amplitude Flatness and Bandwidth
•Adjusting 50 Ω Passband Amplitude Flatness and Bandwidth
•Adjusting 1 MΩ Passband Amplitude Flatness and Bandwidth
3. Verification—Verify the existing operation of the device. This step confirms whether the
device is operating within the published specification prior to adjustment.
4. Adjustment—Perform an external adjustment of the calibration constants of the device.
The adjustment procedure automatically stores the calibration date and temperature in the
nonvolatile memory to allow traceability.
5. Re-verification—Repeat the Verification procedure to ensure that the device is operating
within the published specifications after adjustment.
Test System Characterization
The following procedures characterize the test equipment used during verification.
Notice The connectors on the device under test (DUT) and test equipment are
fragile. Perform the steps in these procedures with great care to prevent damaging
any DUTs or test equipment.
Zeroing the Power Sensor
1. Ensure that the power sensor is not connected to any signals.
2. Zero the power sensor using the built-in function, according to the power sensor
documentation.
