PMM 9030 Frequency Extension
The Sweep mode function is divided into five sub windows:
• Measure
• Limit
• Display
• Marker
• Load Store
Always use Esc button to return to the previous view/condition.
The Measure button is used to set the scan parameters and to run the
sweep.
After having chosen the frequency band and set all the other parameters it is
possible to run the measurement scan simply touching the Exec Sweep
button.
To make subsequent sweeps with the same setting parameters, simply
press ReDo Sweep. This key is particularly useful after having loaded a
previously stored track (see 10.12.6), as with the Re Do Sweep the original
settings are kept for the new measurement: it is extremely easy to make
comparisons, for example, before and after a modification of the EUT.
Once the scan starts, it can be stopped at any time during the execution by
the Stop function key that appears during the scan.
The Frequency menu features four function buttons:
With the C+D Band the receiver will be set to work in the 30 – 1000 MHz
range. The definition of bands C (30-300 MHz) and D (300-1000 MHz) is a
given in CISPR 16-1-1.
Pressing E Band the receiver will be set to scan the 1 - 3 GHz frequency
band. The definition of band E (1-18 GHz) is a given in CISPR 16-1-1.
Pressing C+D+E Band the receiver will be set to scan the entire band from
30 MHz to 3 GHz.
Using these automatic band settings, the Frequency Step and Resolution
Bandwidth are set automatically according to CISPR standard requirement.
For the Advanced option please see next paragraph.
Please note that to make effective the changes after having selected a band,
the receiver needs to start its sweep.
