Definitions
4: Device (for Channel)
This parameter is used by the analyzer to determine the channel plan to be used when computing the
Frequency/Channel values. The choices are BTS (Base Transceiver Station) and MS (Mobile Station).
However, in the initial release of the EXM test set, measurements are supported only for mobile stations;
therefore, MS should always be selected.
The key path for selecting the Device from the front panel menus is:
[Meas Setup], Acquisition Setup, Radio Setup, Device
5: Frequency / Channel
This parameter sets up the analyzer to match the frequency of the received signal. If the radio standard is
other than NONE, this parameter specifies a channel number appropriate to the radio standard, radio
band, and device specified in the previous three parameters. If the radio standard is specified as NONE,
this parameter specifies frequency in MHz.
The key path for setting the Frequency or Channel from the front panel menus is:
[Meas Setup], Acquisition Setup, Frequency [or Channel]
6: Number of Averages
This parameter determines the number of averages (N) for the acquisition. If N is greater than 1, the
analysis intervals for the acquisition are repeated N times, the acquisition period is extended to
accommodate those repetitions, and the measurement results for the repeated analysis intervals are
averaged from all repetitions.
Repetition of analysis intervals does not require re-triggering. The acquisition is still triggered only once.
The key path for setting the Average Count from the front panel menus is:
[Meas Setup], Acquisition Setup, Avg Number
NOTE The Number of Averages must not be greater than one when the Measurement Bit Mask
(page 32) includes Basic IQ Data.
7: Peak Power
This parameter specifies the highest power level that will be received from the DUT during this
acquisition, in dBm. The information is used by the Auto Set RF Level algorithm to determine the upper
limit of the dynamic range.
The key path for selecting the Peak Power from the front panel menus is:
[Meas Setup], Acquisition Setup, Peak Power
