can help you choose the technique best suited to your specific measurement needs.
The Keysight 3458A supports three techniques for measuring true rms AC voltage, each offering unique
capabilities. The desired measurement technique is selected through the SETACV command. The ACV
The following section provides a brief description of the three operation modes and a summary table that
Operation Modes Descriptions
SETACV SYNC Synchronously sub-sampled computed true rms technique.
This technique provides excellent linearity and the most accurate measurement results. It
requires that the input signal be repetitive (not random noise, for example). The bandwidth in
this mode is from 1 Hz to 10 MHz.
SETACV ANA Analog computing true rms conversion technique
This is the measurement technique at power-up or following an instrument reset. This mode
works well with any signal within its
10 Hz to 2 MHz bandwidth and provides the fastest
SETACV RNDM Random sampled computed true rms technique
条件：wideband noise measurements. The bandwidth in this mode is from 20 Hz to 10 MHz.
This technique again provides excellent linearity; however, the overall accuracy is the lowest
of the three modes. It does not require a repetitive input signal and is therefore well suited to

General Information
条件：below to help you select the setup best suited to your specific application.
The Keysight 3458A supports three independent methods for signal digitizing. Each method is discussed
DCV 标配 DCV 功能
This mode of digitizing allows signal acquisition at rates from 0.2 readings/sec at
28 bits resolution to 100 k readings/sec at 16 bits. Arbitrary sample apertures
from 500 ns to 1 second are selectable with 100 ns resolution. Input voltage
ranges cover
100 mV to 1000 V full scale. Input bandwidth varies from 30 kHz to
150 kHz depending on the measurement range.
DSAC Direct sampling AC coupled measurement technique
In these modes the input is sampled through a track/hold with a fixed
2 ns
aperture which yields a
16-bit resolution result. The sample rate is selectable from
6000 sec/sample to 20 μs/sample with 100 ns resolution. Input voltage ranges
cover
10 mV peak to 1000 V peak full scale. The input bandwidth is limited to 12
SSAC Sub-sampling (effective time sampling) AC coupled
These techniques implement synchronous sub-sampling of a repetitive input
signal through a track/hold with a 2 ns sample aperture which yields a
16-bit
resolution result. The effective sample rate is settable from 6000 sec/sample to 10
ns/sample with 10 ns resolution. Sampled data can be time ordered by the
instrument and output to the GPIB. Input voltage ranges cover
10 mV peak to
1000 V peak full scale. The input bandwidth is limited to 12 MHz.
