Configure Gate Mode

The "Configure NRP-Z Analysis" dialog is divided into several sections. The "Gate Mode…" button in the middle section opens the dialog for time gate settings.

For time measurement mode only.

Almost all R&S NRP sensors also support time gated measurements of peak and average power (see the data sheet or operating manual of the respective sensor). Two user-configurable gates can be assigned to one of the traces. Both gates are active at the same time. The values are calculated from the trace data, the time resolution is determined by the resolution of the sensor. An external trigger signal or signal triggering is required for synchronization.

The following graph shows two measurement examples, one with separated gates, and another one with overlapping gates.

The start and stop time of the gates are indicated as gate markers, a bar between the start and stop marker shows the gate length. The indication state of the gate borders and measurement values is only available for certain diagram views which are switched with the "REARR" key. The "REARR list NRP-Z Analysis" dialog provides a selection of views, between which is toggled (see"REARR list - Power Analysis" ).

In the remote control mode, commands for setting the indication state differ from the commands for reading the measurement values.

Trace - Gate

Selects the trace to which the gates are assigned. The sensor assignment to the respective trace is performed in the measurement diagram (trace buttons). The two gates are assigned to the same trace.

Remote command: 
 
Indication

(time measurement mode only)

Indicates the type of R&S NRP power sensor assigned to the selected trace. This field is automatically updated if the sensor is connected or disconnected. Additionally, this sensor is indicated on the trace button in the measurement diagram.

Remote command: 

n.a.

 
State - Gate

Enables time gated measurement. The measurement is started with the "Start" button in the main measurement diagram. Both gates are active at one time.

The gate borders and the measurement values (average and peak power) are indicated in/below the measurement diagram. The indication is only available for certain diagram views which are switched with the "Rearrange" key.

Remote command: 
 
Start / Stop - Gate

Sets the start and the stop times for the respective gate.

Remote command: 
 
Diagram... - Power Analysis

Returns to the "NRP-Z Analysis" diagram.
