  • Page 90 10.11 - Analyzer Mode Operating Instructions 10.11.1 Introduction To enter in the ANALYZER Mode it’s enough to depress the Analyzer soft key on the main screen. In this mode the receiver works as a powerful Spectrum Analyzer and the display shows the "spectrum analysis" (span max 3 GHz) in the frequency domain of a signal tuned at a given frequency.
  • Page 91 The Spectrum mode function is divided into five sub windows: • Frequency • Resolution Bandwidth • Level • Marker • Wide Mode The fifth button is used to change the spectrum view to wide screen mode, as shown in the picture 4-1, and with the Esc button the original view can be restored.
  • Page 92 The Level function has 5 sub-menus, each one with several options. 10.11.4 Level Pressing the Display button it is possible to set two parameters: the visualized Dynamic range (chosen between 80, 100 and 120dB) and the Reference Level, that can be increased or reduced by steps of 5dB within the range +55 dBµV to 90 dBµV (-50 to - 15 dBm).
  • Page 93 10.11.4.2 Misc Under the Miscellanea functions menu it is possible to activate or exclude the Preselector filters and also to set the Tracking Generator. The Preselector is composed by a group of filters automatically selected by the PMM 9030 while it is sweeping or anyway measuring. The aim of the preselector is to reduce the amount of out-of-band energy entering in the receiver, thus helping a lot in reducing intermodulation problems and similar undesired behaviors.
  • Page 94 When using a transducer to make a measurement – a Voltage or Current 10.11.4.4 Conversion Probe, an Antenna, etc. – there is always the need to add to the measured factor values the conversion factor of the transducer in use. The Conversion factor may also take proper account of losses as cable loss, attenuators added externally to the receiver, etc.
  • Page 95 10.12 - Sweep Mode Operating Instructions 10.12.1 Introduction The Sweep mode is used to operate the PMM 9030 as a powerful scanning receiver. To enter in this mode it’s enough to depress the Sweep soft key on the main screen, and immediately the scan setup window pops up and allows the operator to set the parameters for the scan.

The User can also decide which resolution bandwidth use simply selecting either one of the 2 bands available: 120 kHz or 1 MHz. The Start and Stop frequency buttons can be used to set any frequency interval for the measurement;...

  • Page 105 The Tracking generator is an internal, high stability and accuracy, 50 Ohm RF generator ranging from 10 Hz to 50 MHz. It is a CW signal source tuned at the frequency set under the RF OUT Freq window. As usual, to set a given frequency it is therefore enough to edit the value with the soft keys and the left an right arrows, confirming the selections entering the units value (kHz, MHz or GHz).
