Datasheet

16.3. Limit
Set the level for Channel Power and Power Density measurements.
Press Limit key to display the status of Level, including the Total Level, Channel Power Level and
Power Density Level. Default is Off. Only enable the Total Level, the Channel Power Level and
Power Density Level will be displayed.
If you want to set the Level Parameters for Channel Power measurements, first make the Channel
Power Level to be On, there will be two options Power Max and Power Min.
CP Max ：set the maximum of level
CP Min ： set the minimum of level
For example, to measure a transmitter module with the power channel ranges from - 10dBm to
0dBm, you can set the max. power to be 0dBm and min. power to be -10dBm.
The setting for Power Density Level parameters is same.
16.4. Adjacent Channel Power (ACP)
Measures the powers of the main channel and adjacent channels as well as the power difference
between the main and each of the adjacent channels. The adjacent channels have same channel
bandwidth with the main channel, or set user’s demand.
Select ACP measurement under Meas function and press Meas Setup to set corresponding
parameters, which includes Integ BW, Offset/Limits, Meas Type, Total Pwr Ref and Limits.
16.5. Integ BW
Sets the bandwidth for main channel
16.6. Offset/Limits
Includes Offset, Offs Freq, Ref BW, Neg Limits, Pos Limits, En.
Offset
selects one to six adjacent channels.
Offs Freq
sets the frequency of offset carrier
Ref BW
sets the bandwidth for adjacent channels
Neg Limits
sets the threshold parameters for left adjacent channels
Pos Limits
sets the threshold parameters for right adjacent channels
En：
opens or closes the adjacent channels from one to six channels
16.7. Meas Type
Selects measurements type as Total Pwr Ref or PSD Ref. Default is Total Pwr Ref.
16.8. Total Pwr Ref
Sets total power reference to be Manual or Auto
Auto the total power reference is set automatically
Manual the total power reference is set manually
16.9. Occupied Bandwidth (OBW)
Calculates the power within the whole bandwidth by integral operation and computes the occupied
bandwidth by this value based on the specified power ratio. Default occupied bandwidth percentage
is 99%.
Select OBW measurement under Meas function and press Meas Setup to set corresponding
parameters, which includes Max Hold, % Pwr, OBW Span, n dB and Limits.
