value, a resolution and a source list. These parameters must be entered in the
specified order. If parameters are omitted, they default from the right. The
parameter DEFault is used as a place holder.
.The expected power and resolution parameters are defaulted, leaving them at
their current settings. The measurement is carried out on the current window.
Example 3 - Specifying the Expected Power Parameter
The previous example details the three optional parameters which can be used
with the MEASure? command. The first optional parameter is used to enter an
expected power value. The value entered determines which of the power
sensor’s two ranges is used for the measurement. If the current setting of the
power sensor’s range is no longer valid for the new measurement, specifying
the expected power value decreases the time taken to obtain a result.
The following example uses the expected value parameter to specify a value of
–50 dBm. This selects the power sensor’s lower range (refer to “Range” on
page 26 for details of the range breaks). The resolution parameter is defaulted,
leaving it at its current setting.
Example 4 - Specifying the Resolution Parameter
The previous examples detailed the use of the expected value and source list
parameters. The resolution parameter is used to set the resolution of the
current window. This parameter does not affect the resolution of the data,
however it does affect the auto averaging setting (refer to Figure 1- 3).
The following example uses the resolution parameter to specify a resolution
setting of 3. This setting represents 3 significant digits if the measurement
suffix is W or %, and 0.01 dB if the suffix is dB or dBm. Refer to Chapter 2,
“MEASurement Commands”on page 65, for further details on the resolution
parameter. The expected power and source list parameters are defaulted in
the example. The expected power value remains unchanged at its current
