Gated Sweep Overview
Description
The Gated Sweep mode allows a trigger signal to dictate when the spectrum analyzer can sweep. This mode is useful for characterizing signals that are pulsed on and off, such as RF burst transmissions or for measuring spurious noise levels between transmission bursts.
Overview
1.
The trigger signal must be synchronized to the period of the input signal (shown as RF burst below).
2.
The start of the gate time is produced from the positive or negative edge of the trigger signal + the delay time.
3.
The end of the gate time is determined by the set gate length.
4.
The gated sweep should not be positioned at either end of the transmission.

Trace Detection Mode
Description
Each time the spectrum analyzer samples data for each point on the trace, a number of samples are usually taken for each point, known as a sample bucket. The actual value of each point is determined by the detector from the samples in each bucket.
Each selected trace, (1, 2, 3, 4), can use a different detection mode.
Detection modes Auto
Normal
Peak+
Automatically chooses an appropriate mode based on the values of all the samples.
While the signal level is constantly increasing or decreasing, the positive peaks are detected. Otherwise, the detection mode switches between positive peak and negative peaks. Useful for picking up burst phenomenon while avoiding excessive noise.
Detects positive peak signals by selecting the maximum peak value for each point from each bucket. This mode is useful for sinusoidal signals.

Spectrum Emission Mask Overview
Description
SEM measurements are used to measure the out-of-channel emissions relative to the inchannel power. SEM measurements are usually calculated for specified power bands at a number of different offsets to the carrier frequency. SEM measurements are often carried out for a number of different wireless standards.
For 3GPP, the GSP-9300B supports BS (base station) and UE (user equipment) testing standards for both FDD (frequency-division duplexing) and TDD (time-division duplexing) modes.
The GSP-9300B also supports SEM testing for
802.11b, 802.11g, 802.11n and 802.16 as well as user defined emission mask testing

P1dB Normalization
Description
The normalize function is used to compensate for any loss from a long cable that may cause inaccurate measurements.
This function relies on the DUT being directly connected to either the TG or the RF input. The position of the long cable in relation to the DUT
(input or output) will affect the P1dB measurement.
If the cable is at the DUT input, then the line loss of the cable will reduce the output of the
TG before it is input to the DUT. This configuration (Location = Prev) can affect the position of the P1dB point if not normalized.
Likewise if the cable is connected to the output of the DUT, then the gain of the DUT will be reduced at the RF input by the line loss of the cable. In this configuration (Location = Post) the
P1dB point will not be affected.
Note
If a DUT cannot be directly connected to the TG output or the RG input, try to use the shortest cable possible to reduce the effect of cable loss.
The line loss from short cables cannot be measured when using the Normalize function.
