150C CRYSTAL IMPEDANCE METER SAUNDERS AND ASSOC.
The 150C Crystal Impedance Meter is a solid state crystal test set that contains a microprocessor controlled counter which provides display of power, resistance, capacitance and frequency.
The 150C has a internal time base of 10 MHz plus an external input settable to accept 100kHz, 500kHz, 1MHz, 5MHz or 10MHz. It also features remote TTL interface and a 8-digit digital display. The 150C covers a frequency range of 1 to 60MHz in six bands. Crystal termination is 24-ohm source, 27-ohm load. Crystal power is adjustable 50 to 5000 W (1-40MHz), 500 to 1000 W (40 to 60MHz) the crystal is operated at constant power (independent of resistance or frequency variation).
Crystal resistance: max of 500-ohms at 1MHz decreasing to 100-ohms at 60MHz. The capacitance meter measures the value of load capacitor in a range of 0 to 250 pF. The load capacitance is settable with the internal capacitance meter in a range of 16 to 110 pF.
