Xprotolab Specs

[Brian Hawes]

I noticed that in the space of two days, their stock went down from 16 to 5. They are now out of stock
until the end of the Month.
Is that all down to AMRAD?
I think I am going to need more of these!

  I asked the company about input levels and received this info.

  I'm thinking of adding one to my DX crystal set, a narrow band
Panadapter - of sorts.
It might be useful for detecting low level audio signals.

--------------------------------------------------------------------------------------------

The input has 7 gain settings, the screen has 4 divisions:

78.125 mV/div   ==>  312.5 mV   max signal
0.15625 V/div   ==>  625 mV     max signal
0.3125 V/div    ==>  1.25 V     max signal
0.625 V/div     ==>  2.5 V      max signal
1.25 V/div      ==>  5 V                max signal
2.5 V/div       ==>  10 V       max signal
5 V/div         ==>  20 V       max signal

The offset position can be adjusted up and down, for example, if you have a
signal that swings from 0 to 2.5V, you would set the position at the bottom
of the screen and set the 0.625V/div gain setting. If the signal swings from
-1.25V to +1.25V, you would set the position at the center of the screen.

The input impedance is 1M ohm.

Gabriel
