each input line read to allow interaction
with external equipment. Extra line acts
as trigger input

points, may be
organized as 1×32k,
2×16k, 3×10.6k, 4×8k,
etc.
Max Storage Rate
From LIA
up to 1000 16-bit
values per second
From ADC1 up to 40,000 16-bit
values per second
User Settings
Up to 8 complete instrument settings
can be saved or recalled at will from
non-volatile memory
LabVIEW Driver Software
A LabVIEW driver for the instrument is
available from the
www.signalrecovery.com website,
offering example VIs for all its controls and
outputs, as well as the usual Getting
Started and Utility VIs. It also includes
example soft-front panels built using these
VIs, demonstrating how you can
incorporate them in more complex
LabVIEW programs.
SIGNAL RECOVERY Acquire
Software (see page 56)
Users who do not wish to write their own
control code but who still want to record
the instrument’s outputs to a computer file
will find the SIGNAL RECOVERY Acquire
Lock-in Amplifier Applications Software,
available at a small extra cost, useful. This
32-bit package, suitable for Windows XP/
Vista, extends the capabilities of the
instrument by, for example, adding the
ability to record swept frequency
measurements. It also supports the
internal curve buffer, allowing acquisition
rates of up to 1000 points per second
independent of the computer's processor
speed.
Interfaces
RS232 and GPIB (IEEE-488). A second
RS232 port is provided to allow “daisy-
chain” connection and control of up to 16
units from a single RS232 computer port
