  • Page 15: Dc Power Version

    1. AC version (if your back panel looks like the one on the previous page) Connect the 930i to a 115/220 V AC power source via a 3-prong power cord. The power connector is located next to the red ON/OFF rocker switch at the rear of the 930i.

  • Page 16: Cold Booting

    N.NN is the version of software installed in the unit. Note the status of the LEDs on the front panel. If an error has been detected, all of the LEDs will be lit. Turn the 930i off and perform a cold boot.

  • Page 17: 2-4.1 Hardware Cold-Boot

    A successful cold boot will return the 930i to its default settings and erase all stored items. 2-5 VENTILATION The 930i is cooled by air drawn into the fan inlet on the lower left-hand side of the rear panel and expelled through the ventilation holes at the top right-hand corner.

    2. Short the 2-wire side of the hybrid using a jumper cable. (If you cannot access the Hybrid, leave the THL at the default of 0 dB in step 4.) 3. Press the Return Loss function key on the 930i. Use ERL or OSC with a frequency of 1020 Hz. This is mid-band for the measurement.

  • Page 39: 3-2.5 Measure Tone Function Key

    Initially, the 930i displays the measurement in dBm and always returns to dBm when cold booted. If the reading seems too high or low, make sure the reading is in dBm and not dB or dBm0. In Loop and Ground Start Contact modes, the position of the hookswitch will affect the AC Termination, and therefore, the measured level.
