manual abstract
Send a 0 (zero) following the command to set the channel power measurement in the current setup. Send a 1 (one) to set the channel power associated with the trace that was most recently uploaded by command #36, Upload Sweep Trace. If Option 6 is installed and the frequency converter module is attached, the frequencies should be scaled by the scale factor of the module. If the module is not attached, frequencies are sent in Hz. Use Control Word A203 to determine whether a module is attached and the appropriate scale factor. Note that if the channel power measurement is turned ON, all other measurements (field strength, adjacent channel power) are turned OFF. Bytes to Follow: 14 bytes 1) Channel Power Location (0 = current setup, 1 = last uploaded trace) 2) Channel Power Measurement State (On/Off) 3-6) Center Frequency 7-10) Integration Bandwidth 11-14) Span Frequency Site Master Returns: 1 byte 1) 255 (FFh) Operation Complete Byte 224 (E0h) Parameter Error 238 (EEh) Time Out Error Site Master PM Read Channel Power – Control Byte #86 (56h) Description: Read the current channel power or the channel power of a stored trace. Send a 0 (zero) following the command to read the current channel power measurement (i.e. the one that is updated as the unit is sweeping). Send 1-200 to read the channel power associated with a stored trace (use Query Trace Names, #24, to obtain trace numbers). If Option 6 is installed and the frequency converter module is attached, the frequencies should be scaled by the scale factor of the module. If the module is not attached, frequencies are sent in Hz. Use Control Word A203 to determine whether a module is attached and the appropriate scale factor.

Send a 0 (zero) following the command to set the channel power measurement in the current setup. Send a 1 (one) to set the adjacent channel power associated with the trace that was most recently uploaded by command #36, Upload Sweep Trace. If Option 6 is installed and the frequency converter module is attached, the frequencies should be scaled by the scale factor of the module. If the module is not attached, frequencies are sent in Hz. Use Control Word A203 to determine whether a module is attached and the appropriate scale factor. Note that if the ACPR measurement is turned ON, all other measurements (field strength, channel power) are turned OFF.
