DIGITAL METER OF AMPLITUDE FREQUENCY RESPONSE Russian patent published in 2014 - IPC G01R29/06 

FIELD: measurement equipment.

SUBSTANCE: proposed invention relates to measuring equipment, in particular, to amplitude frequency response measurement. A digital amplitude frequency response meter comprises an indicator, a microcontroller, an analogue-to-code converter with its output being connected to the microcontroller input. The first microcontroller output is connected to the indicator. The device also comprises a code-to-analogue converter, an input device and an interface device with its first input being the meter input and the first output being the meter output. The second output of the interface device is connected to the first input of the analogue-to-code converter with the second output of the latter being connected to the second output of the microcontroller. The second microcontroller input is connected to the input device. The third microcontroller output is connected to the third input of the interface device, the fourth microcontroller output is connected to the input of the code-to-analogue converter with the output of the latter being connected to the second input of the interface device.

EFFECT: expanded functionality due to the possibility of AFR measurement.
