Typical Characteristics
NOTE f is the measurement frequency in MHz. The incremental error is available at the frequency
range 1 MHz to 15 MHz, and incremental error applies after the completion of
ZERO-OPEN/SHORT compensation.

*1.There are some cases where the actual incremental error exceeds this limit when this fixture is used with an 4192A
or 4275A.
*2.The maximum measurement frequency of the 4277A and 4278A is 1 MHz, so the incremental error is available
only for 1 MHz measurements.
