Replacing the 8753ES with the E5070A/E5071A
Important Functional Differences

Calibration

The types of calibration kits supported by the 8753ES and E5070A/E5071A are shown in
Table F-3.

Others
The 8753ES allows only one type of user-defined calibration kit to be saved in the internal
memory. Up to 15 classes can be set up when defining calibration kits, including 12 classes
(isolation included) to be used for full 2-port calibration and three calibration classes
(THRU, reflect, and line/match for TRL*/LRM* calibration. A maximum of seven
standards can be defined for each calibration class.
In contrast, the E5070A/E5071A allows ten types of user-defined calibration kits to be
saved in the internal memory, which includ the five calibration kits registrated beforehand.
When setting up calibration classes, OPEN, SHORT, and LOAD can be set up on each port
and THRU between ports. Only one standard is allowed for each calibration class.
On the 8753ES, supported calibration types include not only measurement port calibration
but also receiver calibration and power meter calibration used in power sweeps. On the
E5070A/E5071A, however, only response calibration, 1-port calibration, and full 2-port
calibration are supported. For three or more ports, full 3-port calibration (Options 313, 314,
413, and 414) and full 4-port calibration (Options 413 and 414) are supported.
ECal
The 8753ES needs a PC interface unit to perform calibration using the ECal module, while
the E5070A/E5071A needs only the main body of the instrument and the ECal module to
perform the same function.
Both the 8753ES and E5070A/E5071A support ECal measurement. However, each
supports slightly different functions. The 8753ES supports enhanced response calibration,
1-port calibration for S11 and S22, and full 2-port calibration. Although the
E5070A/E5071A does not support enhanced response calibration, it does support full
3-port calibration (Options 313, 314, 413, 414) and full 4-port calibration (Options 413,
414), making multi-port calibration possible.
While the 8753ES allows the manual measurement for the THRU standard, the
E5070A/E5071A does not. Furthermore, the 8753ES allows a frequency array or module
information to be read, but these functions are not supported on the E5070A/E5071A.
