  • Page 20: Initial Inspection

    Installation Installation Initial Inspection 1 Inspect the shipping container for damage. If the shipping container or cushioning material is damaged, it should be kept until the contents of the shipment have been checked for completeness and the instrument has been checked both mechanically and electrically.

  • Page 21: Operating And Service Instruction

    The operator’s check is supplied to allow the operator to make a quick check on the power limiters prior to use or if a failure is suspected. DO NOT apply more than 1W average power for N9355B/C, 0.63W average CAUTION power for N9355F, 6W average power for N9356B and 4W average power for N9356C.

  • Page 22: S-Parameter Measurement

    Installation The limiting threshold of the power limiter can be measured using a signal source, a power sensor, a power meter and an attenuator as illustrated in Figure 3-6. Please check the maximum input power of the power sensor. If the output power NOTE from the power limiter exceeds the maximum input power of the power sensor, an attenuator is required to avoid damaging the power sensor.

  • Page 23: Limiting Threshold Measurement

    1 Increase signal source power slowly from below 10 dBm to 30 dBm for N9355B/C/F, or from 25 dBm to 35 dBm for N9356B/C, and observe the output power. 2 Compare your results with the graphs in Figure 2-4.
