晶振阻抗分析仪

Crystal Impedance /LCR Meter Mobile radios ａnd communicators are increasingly expanding their applications into homes ａnd offices. This makes the evaluation of crystal resonator characteristics at higher frequencies and/or lower drive levels more critical. However, conventional crystal impedance meters based on the oscillation method cannot properly meet the current measurement needs due to the following limitations on: . High-end measurement frequency （60 MHz or below） . Applicable power level The HP E4916A is a crystal impedance meter based on the transmission p network method which enables you to: . Test at high frequencies （1 MHz to 180 MHz） . Apply low drive level （0.1 nW to 1 mW, when testing a 25 W DUT with the p circuit）.
