USB Driver Software for the Models Latest version 3.0 digitally-signed
versions suitable for Windows 7 32
and 64 bit, Vista 32 and 64 bit, and
Windows XP 32 bit now available
SIGNAL RECOVERY offers two types of digitally-signed USB drivers suitable for use with the Model 7124, 7270, and 7230 Lock-in Amplifiers. The first, SRUSB.SYS, is suitable for all versions of instrument bootcode and firmware; the second, which uses the National Instruments VISA software, requires that the instrument firmware be version 1.57 or later. If the VISA driver is also to be used to perform firmware updates then the instrument bootcode must be version 1.04 or later. Both types of driver are available in different versions for use on computers running Windows XP 32-bit, Vista 32 or 64-bit, and Windows 7 32 or 64-bit.
In general, we recommend that you install the SRUSB.SYS drivers except if you want to operate these instruments from LabVIEW via USB, in which case you should install the VISA drivers. Note however that in order to use the VISA drivers you will also need to download and install the full VISA software package from the National Instruments website. It can be obtained by clicking here.
Note also that the latest version 3.0 SRUSB.SYS driver is also suitable for use with the Model 3820 Universal Counter, Model 3830 Multiplexer, and FASTFLIGHT-2 (Operating software version 1.5.0 or later)
