3.4 RBW Filters
3.4.1 MIL Filters
With the Peak, RMS and AVG detectors the smallest settable
measurement time depends on the RBW.
If several detectors are used contemporarily the Hold Time should be set
to meet the requirement of the slowest one, so that the results of the
measurement are correct for all them.
When a frequency change or an attenuation variation occurs, PMM ER8000
waits automatically the time needed to the internal circuits to overcome the
transient before the measurement time starts again.
The Resolution Bandwidth box is used to select the bandwidth of the
measuring filter.
The drop-down menu allows the User to select from the list, the filter desired.
These filters are mathematically modeled using digital techniques and,
concerning the 200 Hz, 9 kHz and 120 kHz, they are compliant to the CISPR
16-1-1 standard.
Other additional -6dB bandwidth filters are also available: please refer to the
instrument specifications paragraph for the complete list.
The 100 Hz, 1 kHz, 10 kHz and 100 kHz provided filters are MIL-STD-461E
(they are not optional but always available).
When a non-CISPR filter is selected, the Quasi Peak, C-RMS and C-AVG
detectors are disabled.
