    Frequency divider (less than 1MHz)

    Thank you so much, all of you! I am really impressed by all of your invaluable support and help. I am not sure if I can do all the circuitry on myself! Any idea if we can get help somewhere or order it to some place? Thanks, Ehsan

    Frequency divider (less than 1MHz)

    @hevans1944 thank you so much for the detailed reply. I am using Asylum AFm, a MFP-3D with ARC2 controller. I am sure that ARC2 has two digital lock-ins. We are in contact mode and at the two sides of the resonance (contact resonance freq. between f1 and f2). Unfortunately, f1 and f2 are...

    Frequency divider (less than 1MHz)

    Thanks for the note. I will try to be more specific here. I am working with an atomic force microscope and the signals I get are generated in the controller of the AFM (see the attached diagram of the ARC2, specifically the FPGA and DSP parts). As far as I know, the controller has two DDS that...

    Frequency divider (less than 1MHz)

    What I mean is that the 150 kHz and 150/4 kHz signals are phased locked while 160 and 160/4 kHZ are also phased locked separately. Ehsan

    Frequency divider (less than 1MHz)

    Thank you so much, all for your support. Let me clarify and be more specific on the source of the signal and what I need: Two Direct Digital Synthesizers (DDS) are used to generate two waveform at different frequencies (one at 150 and one at 160 kHz, phase aligned ). These digital signals are...

    Frequency divider (less than 1MHz)

    I am looking to buy/biuld a frequency divider (division factor 4) that has the following characteristics: Input signal: Sine wave- frequency in range of less than 1MHz (usually in range of 100-300 kOhm) input level >14dBm Output signal: Sine wave- Amplitude should have a level of around...
