Why does the Analog Input Frequency Test fail in the DSA Calibration Executive Procedure?

Primary Software: Calibration Executive
Primary Software Version: 2.2.1
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: Modular Instruments>>Dynamic Signal Acquisition and Analysis (DSA)

Problem: When I calibrate the DSA board with Calibration Executive, the board fails the Analog Input Frequency Accuracy Test. All the other tests pass.

Solution: The Analog Input Frequency Accuracy Test needs a calibration instrument with the following specifications:

Frequency Range: 20 Hz - 95 kHz
Voltage Range: 3 Vrms
Frequency Accuracy: ± 6 ppm

The Frequency Accuracy is the sum of all errors, including the initial accuracy and stability error.

National Instruments recommends the Agilent 3324A and Agilent 3325A. For other calibrators, compare their specifications with those listed above.
