KH7700
Quartz Crystals Temperature Test System
with

PI - network Measurement

New State of the Art Features
? Multi-Tasking operation in Microsoft Windows? allows testing in background while generating reports and graphs
by operator
? Test limits such as Temperature range and ppm can be changed after actual testing, this gives better reports and
graphs presentation for customers
? Support both “Direct impedance measure” & “Phy. CL “ for FL measurement (Optional Phy CL head)
? User Programmable Drive Level : 10nW - 1mW ( max and min power depends on Rr of crystal )
? Crystal Measurement through passive ? network techniques with KH1800 / KH1820 network analyser
? Multiple crystal types may be accommodated in the same temperature run
? Automatic C0 cancellation for high frequencies
? User friendly system operation including menu driven, mouse operation and easy system calibration
? Perform pass/fail testing to user specified limits
? Stacked dual row test wheels can hold up to 508 crystals per chamber ( depends on crystal type )
? Measures : Fs, FL, Rs, CL, C0, C1, L1, Q, Ts, C0/C1, DF, DLD, Spurious scan, Fs/T, and FL/T
? Optional Chinese operating software
