Tenma 72-5015 Function Generator

The Tenma 72-5015 Function generator is a multiple output repetitive function generator.

It is capable producing a sine, triangle or square wave with an adjustable frequency and

amplitude, as well as a digital square wave output. The waveform symmetry and base

amplitude voltage can be modified, as well as setting the frequency to sweep between

two limits at an adjustable rate.

Display and Display mode:

The frequency output display can be set to display the output frequency of the function

generator or can be used to measure an external digital frequency.

The display indicates the frequency and the lit indicator below the display indicates the

frequency range. The EXT button, when depressed, switches the display into counter

mode. Leaving this button out allows the display to indicate the frequency that the

generator is set at. There is also an attenuation button to the right of the EXT button.

This allows the incoming signal to be attenuated, or reduced by 20dB if the signal

amplitude coming in is too large.

The output frequency is controlled by a combination of controls. The range buttons

select the range of the

signal to be generated.

Page 2 These buttons are used in conjunction with the vernier knob to select the desired frequency. This is a continuously adjustable knob that allows the adjustment of the frequency between 0.2 and 2 of the selected frequency range. Waveform Shape: The waveform shape is selected by three buttons located at the upper right hand corner.
Page 3 connect to the unit to obtain your useable signal. The TTL/CMOS outpu jack generates a digital square wave that is representative of the frequency set, with the period matting that of the analog waveform. The voltage on this is adjusted by the Digital adjustment knob. Pushing the knob in locks the output in 5V mode.
