However, at high frequency, current can easily flow between the cable outer conductor (shield) and ground due to stray capacitance. If the connecting cable is long, oscillation can occur due to such properties as cable inductance and isolation capacitance, disturbing frequency response and possibly preventing measurement.

Page 81: Delaying Measurement Start
The measurement start time is set with some delay time period for the FRA5097 frequency response characteristics measurement, so that the transient error can be suppressed at the minimum level. You can set the delay time period at an arbitrary value according to the time constant of the SUT.
Page 82: Integration
The number of integrations (or the integration time period)that is set for the FRA5097 measurement corresponds to averaging operation of input signal waveforms before Fourier integration.
Page 83 The FRA5097 has a special capability called automatic (auto) integration which provides a capability of automatically setting integration times during measurement. The use of automatic integration capability will lead to automatic selection of optimum integration times as well as reduction of measurement period of time.
Page 84: Input Setting
These are to set the detection levels for excessive (over) input signal levels. FRA5097 has the capability of measuring up to 250 Vrms of input signals due to the auto-range capability of the analysis inputs. However, any levels that exceed the levels set here are judged to be excessive (over) input signal levels.

If you switch the oscillator output voltage on or off while [SLOW] is set, the oscillator output voltage changes slowly, but not quickly or instantly. This function of the FRA5097 is especially effective, for example, not to cause shocks to a vibrator when the FRA5097 output is fed to the vibrator via a power amplifier.

There are two types of measurement data files: i.e., raw measurement data (RAW data) and operated measurement data (OPERATED data). RAW data are those which have been obtained through direct measurement by the FRA5097, which may have been processed by equalizing (through menu [Measure][BASIC FUNCTION][EQUALIZING]) and input weighting (through menu [Input][WEIGHTING FACTOR]) functions.
