R&S ESU
Meas Time - Entry of measurement time
The measurement time can be set between 100 µs and 100 s separately for each
subrange. In the case of quasipeak weighting, the minimum is 1 ms. The measure-
ment time can be set independently for each scan range.
With option ESU-K53 (Time Domain Scan) the measurement time range depends
on the selected resolution bandwidth.
Remote command:
Auto Ranging - Activates the autorange function
If 0 dB RF attenuation is used with autoranging, care must be taken that the per-
missible signal level at the RF input is not exceeded.
Exceeding this level would damage the input mixer.
The 0 dB attenuation should under no circumstances be used when RFI voltage
measurements are performed with the aid of artificial networks as in this case very
high pulses occur during phase switching.

RF Atten - Entry of a fixed RF attenuation

R&S ESU automatically sets the input attenuation as a function of
the signal level.
The input attenuation setting of the scan table is used.
