Anritsu S331D, S332D manual Measure OCC BW dB Down Control Byte #97 61h

9-12) Low Frequency OCC BW

13-16) High Frequency OCC BW

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 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.

Bytes to Follow: 4 bytes

1-4) dB down (in 100th of dB, 1234 = 12.34dB)

Site Master Returns: 16 bytes

1-4) OCC BW (frequency 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) (Option 10 only)

Description: Set the Bias Tee function On/Off. If the Bias Tee is turned on, the Site Master returns the results of Bias Tee.

Bytes to Follow: 1 byte

00h - Turns the Bias Tee Off

01h - Turns the Bias Tee On

Site 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 Site Master does not return the results of the Bias Tee until ap- proximately three seconds after the Bias Tee is turned on.
