Model 7410 AC Voltage Reference A Calculable, Transportable AC Reference Traceable to DC Voltage Standards G uildline Model 7410 AC Voltage Reference is a digitally synthesized AC voltage source. It provides 16 Multiple waveform shapes at 16 different frequencies, and at 5 different voltage levels. Precision waveforms stored in non-volatile memory are generated using new technology developed at The National Institute of Standards and Technology (NIST). The model 7410 utilizes two Digital to Analogue Converters (DACs) to generate extremely stable AC Analogue waveforms at frequencies of up to 20 kHz. Up to 512 DC steps are used to generate the output waveform. In operation, data stored in the non-volatile memory for a given waveform is sent alternatively to each of the two DACs. One DAC is set using bytes on all even addresses, while the other is set using all odd addresses. The output of each DAC is time-multiplexed to the output amplifier so that the output of the first DAC is being used to drive the output, while the output of the second DAC is being changed to its pre-programmed next step. By multiplexing the two DACs in this manner, step noise is reduced, 7410 FEATURES resulting in the highest accuracy/stability RMS voltage The 7410 is a precision AC Reference that > Precision AC Reference can be referenced directly to DC voltage > Calibration referenced to DC SOURCE standards. > 16 different frequencies > 16 selectable waveforms Versatility designed into this innovative AC Voltage > External sensing Reference enables the use of an external 10V DC Solid State Reference as the DC reference for the DACs, instead > Voltage range 1 mV to 7.07 V of the 7410's own internal 10V DC Reference. > 100mA O
