2Setting The Measurement Time - R&S ESU Series Operating Manual

R&S ESU
MIN PEAK The MIN PEAK softkey activates the min peak detector.
Remote command:
QUASIPEAK The QUASIPEAK softkey selects the quasipeak detector.
The IF bandwidth is adapted as a function of the frequency range. The coupling of
the IF bandwidth to the frequency range can be cancelled using the softkey CISPR
RBW UNCOUPLED.
Remote command:
AVERAGE The AVERAGE softkey activates the average detector.
Remote command:
CISPR The CISPR AVERAGE softkey activates the weighting average detector according
AVERAGE to CISPR 16-1. The IF bandwidth is automatically set to the required value accord-
ing to the receiving frequency. This coupling can be cancelled by the softkey CISPR
RBW UNCOUPLED.
Remote command:
RMS The RMS softkey activates the rms detector.
Remote command:
CISPR The CISPR RMS softkey activates the weighting rms detector according to CISPR
RMS 16-1. The IF bandwidth is automatically set to the required value according to the
receiving frequency. This coupling can be cancelled by the CISPR RBW UNCOU-
PLED softkey.
Remote command:
CISPR RBW The CISPR RBW UNCOUPLED softkey cancels the coupling of the IF bandwidth to
UNCOUPLED the frequency range with activated quasipeak or CISPR average detector.
Remote command:
4.5.4.2 Setting the Measurement Time
The measurement time can be set with a 2-digit resolution in the range 10 µs to
100 s.
The measurement time is the time during which R&S ESU measures the input sig-
nal and forms a measurement result weighted by the selected detector. The mea-
surement time does not include settling times of the synthesizer and the IF filter.
R&S ESU automatically waits until transients are over.
When the quasipeak detector is used, the minimum measurement time is 0.5 ms.
When the CISPR average detector or the CISPR rms detector is used, the minimum
measurement time is 100 ms. With the average, RMS, or min/max peak detector the
smallest settable measurement time depends on the bandwidth.
