Before turning on power on the PIM Master or on the connected Anritsu handheld instrument, connect the cables between the instruments and the DUT as shown in the diagram in Figure: PIM Master Connection Diagram. A connection diagram is also printed on the PIM Master connection panel.
Note
In most cases, information and parameters can be entered through the keypad, the directional arrows, or the rotary knob. The numeric keypad enters the information directly. The Up and Down arrow keys change a frequency parameter by 1 MHz. The Left and Right arrow keys change the frequency parameter by 10 MHz. The rotary knob changes the frequency parameter in 1 MHz increments. Choose whichever method is most convenient to enter the required information. Refer to your Anritsu handheld instrument User Guide for additional information.
Handheld Instrument Connection and Power Up
A cable harness is part of the standard accessories included with the PIM Master to connect to an Anritsu handheld instrument. Use this cable harness to make the following connections:
1. Connect the USB cable between the USB Type‑B receptacle connector of the PIM Master and the Type‑A USB receptacle connector of the handheld instrument.
2. Connect the N‑Type cable between the RF Out connector of the PIM Master to the RF In connector of the handheld instrument.
Caution
Some handheld instruments contain both a VNA RF port and a SPA RF port. Be sure that you connect the to the Spectrum Analyzer RF In port.
3. Connect the BNC cable between the 10MHz‑OUT BNC connector of the PIM Master to the Ref In BNC connector of the handheld instrument.
4. Connect the Test Port Cable between the Test Port connector of the PIM Master to the device under test (DUT).
Warning
Confirm that connections are secure. High power RF signals are emitted from the test port and can cause bodily injury. Anritsu recommends using a torque wrench for this connection, Anritsu part number 01‑507 and open ends (01‑508 for 1‑inch, 01‑509 for 1.25‑inch). The torque wrench and parts are included in the PIM accessory package, part number 2000‑1637‑R.
This device (DUT) may be the main feeder cable from the tower or a simple jumper cable. The DUT must be connected to a termination device, such as a low PIM termination or an Antenna.
Caution
Do not use a precision load as the termination device because they are not designed to handle the power of the PIM Master and will become damaged immediately.
5. Power on the PIM Master.
6. Power on the handheld instrument and select the PIM Analyzer mode. Refer to the Anritsu handheld instrument User Guide for additional information on selecting the PIM Analyzer mode.
