Accuracy of Frequency Measurement

Figure 6-27:
Error in the frequency
measurement as a
function of the input
voltage

Conditions: integration time 1 s, measurement signal sinusoid.

The maximum input frequency for the frequency measurement depends on
the sampling rate.

Table 6-37:
Sampling rate and input
frequency range.

Conditions:

Excitation greater than 10 % from measurement full scale, duty

cycle 50 %.

Note:

With the harmonic analysis, input frequencies up to 3.4 kHz can be

measured.
