The Anritsu PIM Master is capable of producing 80 Watts of RF power in the cellular communications bands. Users must take precautions to minimize exposure to these RF fields:
Always terminate the PIM output port of the test equipment into a load, a loaded line or a line that will radiate or absorb the energy before beginning a PIM test.
Confirm that the PIM Master RF power is off after a PIM test.
Always confirm that the PIM RF power is off before disconnecting a coaxial connection, otherwise RF burns may result. Immediate burns to fingers or eyes can result from exposure to live connectors.
Ensure all antenna’s under test are placed so that no personnel are exposed to RF levels that exceed the maximum allowable exposure.
SCPI Commands Introduction
The set of commands in this chapter are used to prepare the PIM Master hardware for the selected measurements. These commands activate a specified measurement and set the instrument to a wait‑for‑sweep mode, waiting for an :INITiate command to begin a measurement. Ensure that your PIM Master is in the desired testing Mode before sending SCPI commands.
Example:
A typical command set for the PIM Master would include:
SENSe:PIManalyzer:MODe PIM|PIMSwp|DTP|SPECTRUM_VIEW (Sets mode to PIM vs. Time, Swept PIM, or DTP)
SENSe:PIManalyzer:MODe? (Responds with PIM|PIMSwp|DTP|SPECTRUM_VIEW, representing mode type PIM vs. Time, Swept PIM, DTP, or SPECTRUM VIEW.)
[SENSe]:PIManalyzer:FREQuency:F1 1930000000 (Sets F1 to 1930 MHz)
[SENSe]:PIManalyzer:FREQuency:F2 1990000000 (Sets F2 to 1990 MHz)
[SENSe]:PIManalyzer:AUTorange 1 (Sets Amplitude to Auto Range)
[SENSe]:PIManalyzer:IMD:ORDer 3 (Sets center frequency of Rx to IM3)
[SENSe]:PIManalyzer:OUTPut:POWer 20 (Sets power to 20 Watts)
[SENSe]:PIManalyzer:TEST:DURation 10 (Sets the POWER ON time)
INITiate:PIManalyzer:MEASure ON (Starts PIM measurement)
