Adjustments and Performance Tests
Introduction
This section describes the Adjustments and Performance Tests required for the E4915A/E4916A
Crystal Impedance / LCR Meter to operate within its speci cations. These adjustments
and performance tests should be performed along with periodic maintenance to keep the
E4915A/E4916A in optimum operating condition. The recommended calibration period is 12
months.
