18: Acquisition Integration
This optional parameter is used to extend the frequency span and dynamic range capabilities of the
sequence analyzer. There is an IF bandwidth limitation of 40 MHz per acquisition, but it is possible to
divide a measurement across multiple acquisitions in order to capture a larger total bandwidth. The
Acquisition Integration parameter specifies how a given acquisition is to be integrated into a set of
acquisitions.
Measurements which support integration of acquisitions for the purpose of frequency span extension are:
SEM, ACP, and OBW.
Measurements which support integration of acquisitions for the purpose of dynamic range extension are:
TD-SCDMA PvT and LTE-TDD PvT.
Other measurements are performed only on a Normal or Primary acquisition type.
The possible settings are:
• NORMal: this is acquisition is complete in itself; it is not integrated with other acquisitions.
• PRIMary: this acquisition is integrated with acquisitions which follow it, for purposes of extending
its frequency span or dynamic range. (Results are stored in this acquisition, not in the Upper, Lower,
or Range acquisitions with which it is integrated.)
• LOWer: this acquisition is integrated with the last Primary acquisition which precedes it in the
sequence, in order to add a lower extension to the frequency span of the primary. Parameter settings
for this acquisition match those of the primary, except that the Input Trigger is set to Free Run, and
the Center Frequency is equal to the Center Frequency of the Primary minus the IF Bandwidth of the
Primary.
• UPPer: This acquisition is integrated with the last Primary acquisition which precedes it in the
sequence, in order to add an upper extension to the frequency span of the primary. Parameter settings
for this acquisition match those of the primary, except that the Input Trigger is set to Free Run, and
the Center Frequency is equal to the Center Frequency of the Primary plus the IF Bandwidth of the
Primary.
• RANGe: this acquisition is integrated with the last Primary acquisition which precedes it in the
sequence, in order to add a lower extension to the dynamic range of the primary. Parameter settings
for this acquisition match those of the primary, except that Input Trigger is Free Run, Peak Power is
-40 dBm, and Expected Power is -70 dBm.
