Coupling
Press the Coupling softkey to select the input coupling type.
–DC
DC coupling allows both the AC and DC analog input signals to pass through to the analog analyzer and to be measured
down to 0 Hz. This setting should be selected when making DC voltage measurements.
–AC
AC coupling blocks the DC component of the analog input signal by switching a capacitor in series to the input path.
This setting should be selected when you need to measure only the AC component of a signal. For example, use AC
coupling when you are making an rms or peak-to-peak voltage measurement.
Band width
Press the Bandwid th softkey to select the input bandwidth value.
– 90 kHz
(This is the default setting with sampling rate of 192 kHz)
– 1.5 MHz
– This setting is only available with Option N3431A. Refer to “U8903B Options” on page 37 for more information.
Reference
Press the Reference softkey to set the input references for analyzer.
–Voltage
– Ratio
– Frequency
– Impedance
–Sound level
–Calibrator level
