Set the instrument to PIM Analyzer mode (refer to Mode Selector Menu or Menu Key). This section is a brief introduction to PIM analysis. For more details, refer to the Passive Intermodulation Analyzer Measurement Guide that is listed in Other Documents.
Preparing for PIM Measurements
Along with your PIM Master, you need tools and components that are provided in the accessory kit, and you need to set up the instrument for your planned measurements.
Checking Required Tools and Components
The following items are supplied with your PIM Master accessory kit or can be ordered separately as individual components. Consult your Technical Data Sheet for part numbers.
To prepare the PIM Master for measuring PIM, put the it in PIM Analyzer mode.
Before calibrating the PIM Master, set the parameters for the four measurement types. This will eliminate the need for recalibrating due to changing parameters. To set up the parameters for the four measurement types, perform these steps. See Passive Intermodulation Analyzer Measurement Guide that is listed in Other Documents for complete instructions for set up and calibration of the instrument.
To set up PIM vs. Time measurements:
1. Press the Measurements main menu key and then press the PIM vs. Time submenu key.
2. Press the Freq main menu key, then select the input frequencies for the F1 and F2 carriers, and then select the intermodulation order.
a. Press the Carrier F1 submenu key and set the desired frequency.
b. Press the Carrier F2 submenu key and set the desired frequency.
c. If necessary, press the Intermod Order submenu key until the desired setting is underlined (3rd, 5th, or 7th).
d. If necessary, press the Band Select submenu key until the desired High or Low setting is underlined (or one of the following with Option 194: PCS or PCS/AWS, Option 600: 1900 MHz or 600 MHz, Option 902: IM2 or GSM).
3. Press the Setup main menu key to set the power level and test duration.
To set up Distance to PIM measurements:
1. Press the Measurements main menu key and then press the Distance‑to‑PIM submenu key.
2. Press the Setup main menu key, then the DTP Aid submenu key.
3. On the DTP Parameters screen, use the touch screen to enter or select values for Distance, Data Points, and Cable type (or enter Cable Loss and Propagation Velocity).
To set up Noise Floor measurements:
1. Press the Measurements main menu key and then press the Noise Floor Measurements submenu key.
2. Choose Time View or Spectrum View and if Spectrum View whether to calibrate.
3. Press Freq key to set.
To set up Swept PIM measurements:
1. Press the Measurements main menu key and then press the Swept PIM submenu key.
2. Choose 1- or 2- Port mode.
3. Choose High or Low band (2-port mode only works with Low band).
4. Select 3rd, 5th, or 7th intermodulation order.
5. Press Swept PIM Aid to set up the markers for Swept PIM measurements.
After setting up the measurement types, visually inspect all RF connectors on the test instrument, the test lead, the PIM standard, and the Low PIM Load. Clean connections each day prior to first use.
Note
Save your instrument settings in a setup file to allow easy recall of frequently used settings.
