INFORMATION
You will find further specifications on the signal generator as well as the
ZFDC-20-5-S+ or ZFDC-20-33-S+ directional couplers in the respective
manufacturer’s documentation.
6.7 Metrological Properties
6.7.1 MSA-600-X/-U
Table 6.1: Metrological Properties of the MSA-600-X/-U
Table 6.2: Maximum object velocity
For measurements with the BWX1 or BWX2 bandwidth extensions, 10 nm is
the limit for the displacement amplitude. For amplitudes < 1 nm, additional
spectral impurities can already be generated in the spectrum.

The attainable frequency resolution depends on the set bandwidth. The minimum frequency resolution is only attained if the
maximum value for FFT lines is selected and the analysis bandwidth is limited.

Valid for amplitude errors < 1 dB for vibrations with a defined frequency.Amplitude errors caused by
digital filtering / demodulation are taken into account.Large amplitudes can additionally cause spectral
impurities in the measurement spectrum which scale with the movement amplitude.
