… digitalinput #1 of the analyzer. You can then use the Digital Interface Analyzer (intervu)program as shown in the accompanying test file example “jitter PSIA BCK to AES BNC.at27.” This test file will…
In this two-part series, we’ll review the features available in APx500 software to help ensure that settled readings are acquired when testing audio devices.
… and measurements of the device’s output THD+N.
An example test of a Digital-to-Analog converter is shown below with a nested sweep of jitter frequency and audio frequency versus measured THD+N, according to…
… APx585/586, the simplest way to add the external resistor is by inserting a BNC-Tee and adapters as shown in Figure 1. For improved noise shielding, a metal shell tied to the connector shield should enclose…
… to which the 2722 is connected (in this example we're using Address #2) and enter the string as shown into the VISA Resource control.
Note: For each VI setting, you can either look at the Front Panel…
… used to set arbitrary decibel reference values. For example, you could set dBrA to 1.0 μV, as shown below and then select dBrA as the units in the Analyzer meter or Function meter. In the figure…
… (root sum of squares) summation of the 9 harmonics relative to the fundamental. The THD number is shown below the spectrum graph when the macro finishes (Figure 2).
A second set of files named "Burst…
… analog balanced inputs of an APx585. When I generate a sine wave signal into the receiver, the APx shows a strangely distorted waveform with a level much lower than expected. What is wrong?
Answer
Most…
… can use the LabVIEW Path to String function to convert a LabVIEW file path to the necessary string, as shown in the modified version of your VI below. The modified example also uses the LabVIEW File Dialog VI to…
