> Model number: AVO-9A-B-P-P3-SLAA
>
> Description: Laser Diode Driver (Pulsed Voltage) with IEEE-488.2 GPIB
> and RS-232 Computer Control Ports
>
> Polarity: positive
>
> Amplitude: 0 - 140 mA (see footnote 3 on datasheet)
>
> Maximum output of mainframe into 50 Ohms: 10V
>
> Pulse width (FWHM): 2 - 50 ns
>
> Maximum PRF: 50 kHz
>
> -P3-SLAA option: Provides an 8-pin socket for the QFLD-840-2SM. The
> positive output pulse is applied to pin 2 of the diode. All other pins
> are grounded. Rseries in the output module is approximately 42 Ohms,
> such that Rseries + Rdiode = 50 Ohms, approximately.
>
> Other: as per the standard AVO-9A-B-P, described at

Notes: Output pulse looks like crap at lower amplitudes; use at least 5 V to minimize weirdness (plan is to always use 10 V, and use fixed RF attenuators to get the right amplitude for each diode). Narrow pulse widths come out narrower than advertised - a setting of 2 ns yields ~1 ns, 3 ns yields 2 ns, 4 ns yields 3 ns, etc. (This can apparently be calibrated - will do sometime if we decide we care.)

output modules

We have two AVX-S1-P3-SLAA (8-pin) and one AVX-S1-P4B (14-pin).

Motor/encoders are Quicksilver QCI-A17H-3 for Z, QCI-A23H-5 for X and Y.

X and Y stages are Lintech 209205 rev. A.
