CHANNEL NUMBER Changes the center frequency of the spectrum analyzer to the frequency of the current channel, and then allows you to enter the channel number for the PHS channel you want to measure. The PHS measurements personality uses the channel number to set the center frequency to the correct value when one of the �channel� measurements is performed. The channel measurements are the measurements accessed by Power , Power vs Time and Adj Ghan Power. Automatically tunes to the channel having the highest carrier power level in the selected station transmit band.. Changes the center frequency of the spectrum analyzer to the frequency of the current channel �X,� and then allows you to enter the frequency of any arbitrary channel that you want to measure. CHAN X CTR FREQ can be helpful if you know the channel frequency but not the channel number, or if you want to measure a frequency that does not correspond to a standard channel number. If you do not enter a frequency, the default frequency of 300 MHz will be used. Using CHAN X CTR FREQ automatically changes the channel number that is shown on the left side of the spectrum analyzer display to an �X. � Allows you to change the center frequency of the spectrum analyzer temporarily. Allows you to select the slot number of the burst that you want to measure. The slot number is used in conjunction with external triggering for the antenna power, carrier-off leakage power, spurious emission, power versus time, and digital demodulator-based measurements. If the trigger is synchronous with the start of the RF burst or from the unique word trigger (TRIG SRC UW EXT set to UW), you should select slot number 1, regardless of the actual slot number being used by the station. A burst trigger may be obtained directly from a personal station or from an RF burst carrier trigger. If the trigger denotes the start of the PHS frame where the burst can be in one of eight slots within the frame, you can set the slot number from 1 to 8. This frame trigger may be obtained from a public cell, other cell, or personal station simulator, or from another piece of test equipment.
