Impedance for Flexmod P3 driver?

[DLProcessor]

Hello,

What is the impedance for the MOD input of the flexmod P3 drivers? How much current would be required for the MOD input? (Is it just simple Ohm's Law?)

Thanks

According to the user manual, the input impedance is 99kΩ so the current required would be a mere 50µA.

Here is the manual: http://hacylon.case.edu/laser/FlexModP3/FlexModP3_Manual.pdf

It says input x is 99 kohms, but for the analog/ttl input, it is not mentioned.

Someone with one of these drivers want to run a quick test?

Of course the 99kΩ is for the signal! It wouldn't make any sense to have 99kΩ for power.

I just measured mine at 98.5kΩ
