Catalog excerpts

The ACH-C can provide chopping rates ranging from 4 Hz to 5000 Hz with the use of two supplied chopper blades. The chopping frequency is measured by an internal crystal-controlled frequency counter and displayed by means of a 4 digit, 0.56" (14 mm) high, green LED display. The display update rate is once per second. Two ranges are provided: 4 to 500 Hz and 40 to 5000 Hz. A TTL/CMOS compatible phase reference signal is provided for use with lock-in amplifiers or other ancillary test equipment. Attachment to the controller is made via a ten foot (3.6 m) coiled modular cable that is detachable at both ends. > Frequency Range 4.0 to 500 Hz (3 slot blade) 40 to 5000 Hz (30 slot blade) Frequency Readout Accuracy: 0.1% of setting 0.1 % of setting / hour Frequency Stability: 1 Hz > 0.01% of setting / hour 2 (Internal Clock) Frequency Stability: 0.1% of setting / hour 2 Hz (External DC Source) Phase Jitter: 0.1% peak-to-peak, 3 slot blade1 % peak-to-peak, 30 slot blade Settling Time to Lock: < 5 seconds for full scale change < 1 second for 10% change External Frequency Input (Hz): TTL/CMOS Compatible, 40 to 5000 External Voltage Control Input: 0 - 4 VDC takes unit through entire speed range Ext.
