Baseband I/Q Inputs (Option BBA) Measurement Concepts
Selecting Input Probes for Baseband Measurements
Supported Probes
The following table lists the probes currently supported by Option BBA:
Probes without Stored Calibration
The following 115xA active probes may be used with the MXA’s
baseband IQ inputs and may use the same probe calibration utility
software. However, the probe calibration data is not stored in the MXA
and will be lost if power is cycled. Use of the E2655B de-skew and
calibration kit, including the calibration fixture, is required because of
the different physical configuration of the probes. (The physical
connections are different mechanically, not electrically.)
Refer to the current Agilent probe data sheet for specific information
regarding frequency of operation and power supply requirements.
