3-22
■
Measurement mode MEAS mode
Value range: 0) CH2/CH1 1) CH2/OSC
Description: Selects the reference signal for frequency response (transfer function)
measures.
With CH2/CH1, the change up to CH2 is measured with reference to
CH1 input.
When CH2/OSC, the change up to CH2 is measured with reference to
the oscillator output. CH1 input terminal is then separated from the
internal and is open.
Initial values: 0) CH2/CH1
■
Integration time MEAS integ. time
Value range: 0.01 - 999.99 s
Description: Specifies the integration time for the signal. The longer, the less
susceptible to noise is the measurement.
The actual integration time is the longer of the shortest signal cycle
duration equal or greater than this value or the integration cycle(s)
separetely specified.
Initial values: 0.02s
■
Integration cycle MEAS integ. cycle
Value range: 1 - 999 cycles
Description: Specifies the integration time for the signal as the signal cycle count.
Initial values: 1 cycle
■
Delay time MEAS delay time
Value range: 0.00 - 999.99 s
Description: Delay time from the point when the frequency, amplitude, or DC bias
is modified to the point when the actual measurement using the
modified values starts. When the system under test exhibits some
latency due to high order filters or the like, accurate measurement
cannot be obtained unless sufficient time is allowed before the
response is stabilized.
Initial values: 0.00 s
