Control Byte #97 (61 H ); Ontrol Byte #98 (62 H ) - Anritsu Spectrum Master MS2711D Programming Manual

Measure OCC BW dB Down – Control Byte #97 (61h)
Description: Measure OCC BW with dB down method.
If option 6 is installed and the frequency converter module is attached, the OBW frequencies will be scaled by the
scale factor of the module. If the module is not attached, the OBW frequencies are sent in Hz. Use Control Word
A203 to determine whether a module is attached and the appropriate scale factor.
Bytes to Follow: 4 bytes
1-4) dB down (in 100
Spectrum Master Returns: 16 bytes
1-4) Occupied Bandwidth (in Hz)
5-8) Measure % of Power (% of power * 100)
9-12) Low Frequency OCC BW
13-16) High Frequency OCC BW
Set Bias Tee Function - Control Byte #98 (62h)
This command is available only with Option 10.
Description: Set the Bias Tee function On/Off. If the Bias Tee is turned on, the Spectrum Master returns the results
of Bias Tee.
Bytes to Follow: 1 byte
00h – Turns the Bias Tee Off
01h – Turns the Bias Tee On
Spectrum Master Returns:
If bias tee is turned Off (1 byte)
1) 255 (FFh) Operation Complete Byte
224 (E0h) Parameter Error: Invalid state
238 (EEh) Time-out Error
If bias tee is turned On (10 bytes)
1) Bias Tee Board Indicator (00h = No Hardware Installed, 01h = Hardware Installed)
2) Bias Tee Current (Highest byte)
3) Bias Tee Current
4) Bias Tee Current
5) Bias Tee Current (Lowest byte)
6) 10 * Bias Tee Voltage (Highest byte) : voltage value is in volt/10
7) 10 * Bias Tee Voltage
8) 10 * Bias Tee Voltage
9) 10 * Bias Tee Voltage (Lowest byte)
10) 255 (FFh) Operation Complete Byte
224 (E0h) Parameter Error
238 (EEh) Time-out Error
Note: Due to the hardware delay, the Spectrum Master does not return the results of the Bias Tee until
approximately 3 seconds after the Bias Tee is turned on.
