Trig-Tek/Astronics 311A Frequency Multiplier Comes with what you see in the pictures. If you don't see it, you probably won't get it. Specifications are from Astronics/Trig-Tek and may vary slightly due to upgrades, options, or revisions this unit may or may not have. This unit ships fully tested and guaranteed to work for 30-days, parts and labor, excluding freight. The Unit's Serial Number Tag Reads: Model Number: 311A Serial Number: 518 Power Requirements: 115 VAC Description: The Model 311A Frequency Multiplier provides a means of multiplying a frequency by a "N" numerator of 0001 to 9999 in integer steps. The Loop is phase locked to an input frequency signal and the output is the exact multiple of the setting at "N". Input Levels from 30 mV to 100 V PK of any recurring wave is required for normal operation. An ERROR LED illuminiates when the loop is not locked. The XN output maximum frequency is one megahertz. If the multiplication of the Input frequency times the "N" exceeds one megahertz, the error light will illuminate. Two 5-Volt TTL outputs bring out the X1 which is the same frequency as the Input and XN which is the Input frequency times the "N" numerator. The signal is brought into the input buffer amplifier. This circuit has protection to guard against damage with inputs up to 110 Volts RMS. The buffered signal is amplified at the limiter to drive the frequency discriminator and phase detector. The frequency discriminator provides a signal which causes the voltage controlled oscillator frequency to be moved toward the frequency of the input signal. When the frequencies are within plus or minus one Hertz, the discrimnator becomes a phase detector with a linear voltage versus phase output. The phase detector, loop filter, voltage controlled oscillator, and selected divider are then a phase-lock-loop system. The phase lock system with teh digital dividers in the loop between the voltage controlled oscillator and the phase detector provides a means of accomplishing exact multiplication of the input frequency by the integer number set for "N". Input Specifications: Frequency Range: 5 Hz to 10 KHz Level: 30 mV to 100 V sine wave, square wave, or pulse Impedance: 100,000 Ohms (guarded to 110 VRMS) X1 Output Signals Specifications: Level: 5 V TTL Impedance: Less than 200 Ohms (25 mA) XN Output Signals Specifications: Level: 5 V TTL Impedance: Less than 200 Ohms (25 mA) ERROR Light: LED illuminates when the Input frequency times the setting at "N" exceeds 1 MHz. Operating Temperature Specifications: Range: 0°C to +70°C Power Specifications: Input Voltage: ±115 or 230 VAC (switch selectable) Power Consumption: Approx. 3 watts Optional - Not included: DC-powered 12 or 24 VDC Dimensional Specifications: Size: 5.25" W x 2.75" H x 6" D (13 cm x 7 cm x 15 cm) For Domestic Customers: Packaging, handling, and order processing included in shipping in all domestic shipments as quoted by the shipping calculator.
