Introduction
This user's guide describes basic operation procedures for the
HP E4915 A/E4916A; ranging from power-on and setup to Cl
measurement. This guide also shows how to access functions available
with the HP E4915A/E4916A. This guide is intended to serve as a
reference for beginning users of the HP E4915A Crystal Impedance
Meter or HP E4916A Crystal Impedance/LCR Meter.
Features of the HP E4915A/E4916A
The HP E4915A Crystal Impedance Meter and HP E49I6A Crystal
Impedance/LCR Meter employ the network analyzer method
(transmission w network method) to determine performance of crystal
resonators. With a built-in receiver similar to that of a network
analyzer and a wide measurement range between I to 180 MHz,
these meters can measure and display parameters that are generally
measured for crystal resonators; resonant frequency Fr, crystal
impedance Cl, and equivalent cirucuit constant.
In addition to the basic measurement functions of the HP E4915A,
the HP E4916A can change the measurement signal level. It also
offers the drive level dependency testing as well as the evaporation
monitoring, LCR measurement, and analysis using filter. The
HP E4916A can also make measurements using the optional probe
001.
The following list shows the difference between the HP E4915A and
HP E4916A.
