[Step Detect]
When the S71710 series CW power sensor is connected, [Step Detect] will be displayed below the current menu. When
the average setting is provided for measurement with the CW power sensor, the “Step Detect” will be set in “On” state.
If the power changes significantly, the data in the buffer zone will be completely cleared, the average setting will be
restarted, and the power displayed on the screen can quickly change to the newly measured value; when “Step Detect” is
set in “Off” state, the data in the average buffer zone won't be cleared. If the power changes greatly, the power displayed
on the screen will slowly change to the newly measured value.
By default, "Step Detect" is in "ON" state. Only when the measured power value is relatively small, e.g. the signal with a
power less than -50 dBm is measured, the average count will be increased and "Step Detect" will be set to "OFF". After a
long period of time, the power of the low power level signal can be measured stably.
[Range]
When the S71710 series CW power sensor is connected, the [Range] will be displayed. The S71710 series CW power
sensor has “High” and “Low” ranges. When the power of the measured signal is greater than
-14 dBm, the high range will be adopted. When the power of the measured signal is less than -13 dBm, the low range
will be adopted.
[Range] includes three setting options: "Low", "High" and "Auto". If [Range] is set as "Low", the low range will be
forcibly adopted, and when the input power is greater than the low range, an error prompt will be given; If [Range] is set
as "High", the high range will be forcibly adopted, and when the input power is less than the low range, the accuracy of
the measurement result can't be guaranteed. By default, [Range] is set as "Auto", therefore, an appropriate range is
automatically selected based on the measured power value.
[Gate Set]
When the S81702 or S81803 series peak power sensor is connected, four gates can be set at most.
[Gate Number]
It is used to select the number of gate to be set. There are four gates in each channel.
[Start Time]
It is used to set the start time of the currently selected gate relative to the trigger time. For example, if the current trace is
triggered in the middle position, the trigger delay is 0, and the “Start time” is set as 0, the vertical line of Mark 1 of the
current gate will be located in the middle of the screen. When the trigger position is changed, the position of Mark 1 will
be changed.
[Length]
It is used to set the time length of the current gate, i.e. the time interval between Mark 1 and Mark 2.
The length of the current
gate can't exceed the screen. If the set length exceeds the screen, the set value will be
automatically defined to the rightmost length of the screen.
If the trigger position is changed, the
“
Start Time
”
and
“
Length
”
of the gate will also be changed and the two marks of
the gate can't go beyond the screen.
