  • Page 2: Do You Have Everything

    Do you have everything? FieldFox –To check for installed options, press System then System Configuration Options then Show Options then Cal Kit – OSL Tee or other calibration devices. USB Power Sensor – For making Power Meter measurements. (Opt 302)

  • Page 3: Battery Usage

    Use ONLY a FieldFox charger to recharge a battery. The battery can be fully charged while in the FieldFox in about 4 hours with the FieldFox either ON or OFF. A fully discharged battery takes about 1.5 hours to recharge to 80%.

  • Page 4: Measure Return Loss (Cat Mode)

    Measure Return Loss (CAT Mode) Starting with A.11.25 firmware, for the B models, the FieldFox output power defaults to -15 dBm. Return loss can be thought of as the absolute value of the reflected power as compared to the incident power.

  • Page 5: Measure 1-Port Cable Loss (Cat)

    5. Connect the DUT. 6. Press Freq/Dist and enter Start Stop frequency. 7. Connect the DUT (cable to be tested) to the FieldFox and connect a LOAD at the end of the DUT. 8. Press Trace 6 then Math and Memory, then Data->Mem.

  • Page 6: Measure Distance To Fault (Cat)

    8. Press Meas Setup 4 then DTF Cable Specifications. 9. Either press Edit/Save/Recall Cables or enter the Velocity Factor Cable Loss manually--using Cable Corr [Manual]--of the DUT. 10. Connect the start end of the DUT to the FieldFox. The DTF measurement is displayed.

  • Page 7: Measure S-Parameters (Na Mode)

    Measure S-Parameters (NA Mode) S-parameter syntax is described by the following: S (out | in) out = FieldFox receiver port in = FieldFox source port 1. Press Preset then Preset 2. Press then Mode then then choose from the following: 1-port reflection measurement.
  • Page 8 Measure S-Parameters (NA Mode) continued The following NA Mode settings can be made before or after calibrating without affecting measurement accuracy. Press Measure 1 then Format to change the format for the measurement. Press BW 2 then Average then enter a value for the number of trace sweeps to average.

  • Page 9: Multi-Trace Configurations (Na Mode)8

    Multi-Trace Configurations (NA Mode) You can display multiple traces on the FieldFox screen. The above image shows a 3-trace configuration. Tr1 is the ACTIVE trace as indicated by the highlighted Tr1 annotation in the upper left corner. The Frequency Range, IF BW, Resolution, Averaging, and Output power is common to all traces.

  • Page 10: Calibration (Cat, Na, Vvm)

    A calibration is performed automatically when the FieldFox is powered ON, CalReady sets the reference plane at the test port connectors. Press Cal 5 then see the FieldFox User’s Guide. Cal Rdy is shown on the screen when a CalReady is correcting the measurement.

  • Page 11: Spectrum Analyzer (Sa Mode)

    Spectrum Analyzer (SA Mode) SA measurements require NO calibration. Check for a Compressed Measurement 1. Using a marker at the signal peak, make note of the signal power level. 2. Increase the RF Attenuation level by 5 dB. If the signal level does NOT change, then NO compression exists.

  • Page 12: Channel Measurements (Sa)

    Channel Measurements (SA Mode) Optionally apply a Radio Standard which changes frequency settings, Res BW, and other relevant settings to that of the selected standard. Then change the frequency range by selecting channel numbers. 1. Press Freq/Dist then More Radio Standard.

  • Page 13: Record Playback (Opt 236)

    Record Playback (Opt 236) Allows you to record SA traces and play them back at a later time. You can change most SA settings during a recording. Setting changes are recorded along with the traces. To record a new session: Press Trace 6 then Record Playback Session,...

  • Page 14: Rtsa Mode (Opt 350)

    RTSA (Real-time Spectrum Analyzer) Mode—Option 350 How to select RTSA Mode Press Mode then Real-Time SA How to make real-time measurements Press Measure 1 then press from the following: Density Spectrum The signal displayed is a real- time spectrum with a histogram bitmap. Spectrogram The signal displayed is a real-time spectrum with a spectrogram bitmap.
  • Page 15 Trig then Type then choose from the following: Free Run - Triggering is provided by the FieldFox internal circuitry. A new sweep begins when the previous sweep ends. External - A sweep is triggered on an external TTL signal at the Ref In/Trig In connector on the FieldFox top panel.

  • Page 16: Power Meter Mode

    Perform external zeroing when measuring power levels below -30 dBm. During external zeroing, the power source MUST either be turned OFF or the power sensor be disconnected from the DUT. Press Cal 5 then see the FieldFox User’s Guide. External Zero Then...

  • Page 17: Save And Recall Files

    Save and Recall Files Save current settings and calibration, trace data (CSV) and .S1P), or a picture of the FieldFox screen. Press Save/Recall 9 Device 1. Then to set the LOCATION where the file is to be saved. Choose from the following:...
