KH1120 / KH1240 PI-Network Crystal Measurment System

High Accuracy IEC444 PI-Network Measurement. Supports "Direct Impedance Measurement" and "Physical Load Capacitance" methods for FL measurement. Microsoft Windows® 95/98/Me operation. Full Network Analyser Configuration with built-in Frequency synthesizer and Vector-voltmeter. Frequency Range : KH1120 : 1-120MHz KH1240 : 20KHz – 400KHz, 500KHz – 240MHz Drive Level : 10nW - 1mW into 25 Ohm. Measurement capabilities (more than 48 parameters): Fr, Fs, FL, Rr, Rs, RL, CL, C0, C1, L1, Q, Ts, C0/C1, DF1, DF2, FL1, FL2, DLD-F, DLD-R, DLD-γ (gamma : IEC444-6 standard), spurious scan. Automatic spurious response measurement. Automatic drive level dependence measurement. Extensible measurement head. Optional test fixture for SMD packages. Optional Test Fixture for Tuning Fork Crystal (For KH1240). Microsoft Windows® operation allows high quality graph and report printout. High speed PASS/FAIL measurement and sorting upto 5 bins ( sorting results displayed on screen ). All sorting limits of each bins are individually programmable by operator. User friendly system operation including menu driven, mouse operation and easy system calibration. Flexible data storage and printing features. Optional multi-language operating software for using in different countries ( Chinese, English, and more ... ). External time base interface. Repeatability : Fs ≤ ± Time base error ± 1 ppm. FL ≤ ± Time base error ± 1 ppm ± (0.2pF × Ts of crystal). Rs ≤ ± 8% ± 1 Ω . Time Base error : exfactory calibration ≤ 1 ppm aging for 1st year ≤ 2 ppm aging for 2nd year and thereafter ≤ 1 ppm Calibration Method : 3 terms (open, short and load) calibration with standard resistor ( provided with system ). Requirements on IBM™ PC compatible computer supplied by user : Minimum Pentium III 300MHz , 3.25” floppy, 64MB RAM, 20M hard disk space , Windows® 95, mouse, 800 x 600 SVGA display adaptor (Pentium III 800MHz or better with Windows 98 is strongly recommended for optimum performance ). Full size PCI slot with +3V and +5V is required
