[By calibrating the gain and offset potentiometer 50 k and 100 k respectively. ]Why now? What did you change?
µF? Really?[Yes; C2 as per the datasheet.
C2 (µF) =100/fFS; if fFS ≤ 100kHz; 0.001; if 100kHz < fFS ≤ 500kHz;
0.0005; if fFS > 500kHz or C2 = 10²/FMAX]
Hi,
I am using Keysight DSO-X 2024A for frequency measurement.
Now I am getting linearity for 0 to 10VDC. I am getting 10kHz for 0 V and 110 kHz for 10V.
Fout= Vin/ 7.5 R1 C1
where; C1= One-shot capacitor(in my case 285 pF)
C2= Integrating capaciotor(909µF)
R1=Input resistor(in my case 40kΩ...
Hi,
Thanks for your reply.
Please find the attachment of the circuit I am using for voltage to frequency conversion.
I have set 10 kHz for 0V and 110 kHz for 10V. For the voltage between 1 to 9, I was getting some random frequency like 310 kHz for 2V, etc.
Also, the Behaviour of the practical...
Hi,
I am using VFC32 as Voltage to frequency. I want to make circuit that will convert 10 to 110 kHz signal in to 0 to 10V.
I was getting 10 kHz for 0V and 110 kHz for 10V but i didn't get linearity.
How to get linerity in VFC circuits.
Thanks.
Regrads,
Kartik patel
