VC2000 - Frequency Counter This VC2000 is an intelligent multi-function instrument which measures Frequency, Pulse counting, Crystal. It has 4 step gate time, 5 range function select and 8 digits display. All functions depend on single CPU, A crystal controlled temperature circuit provides constant compensation for the temperature drifting. Technique specifications: A. Measurement 1. Input terminal There are 3 input terminals on this instrument: CHA. High frequency 50 MHz - 2,4000 MHz CHB. Low frequency 10Hz - 50 M Hz Crystal Oscilloscope: for crystal measurement
Gate Time: 0.1S,1.0S,5.0S, 10S Accuracy: Time base deviation X frequency +- 1 d Progressive Counting measurement 4 steps CHB input terminal resolution: +- 1d, counting frequency: 10Hz - 4Mhz Crystal measurement: Input Features: Input sensitivity for CHA 25mVrms/200m Vrms Input impedance: approx. 50 Ohm Max safety voltage 3 V Input sensitivity for CHB: No.2 range 25m Vrms/80 m Vrms No.3 range 10mVrms/30m Vrms Input impedance: approx. 1 M ohm ( less than 35 pF) Max Input safety voltage: 30V Time base: Short term stability: +- 3 X 10-9/second Long term stability: +- 2 X 10-5/Month Temperature: +- 2 X 10-5/10oC - 40o C Power: 110 - 220V Size: 270 X 215 X100 mm Weight: Approx. 1550 g. |
