This instrument is in very good condition and has been checked for front panel operation of all controls and indicators. It was never used in service and has been stored since purchase.
See links below for PDF files which include an instruction manual for the computer interface command set, an instruction manual for an accessory preamp (not included in this listing), a link for ordering the instrument's instruction manual, and product brochures which describe this instrument.
In its most basic form a lock-in amplifier is an instrument with dual capability. It can recover signals in the presence of an overwhelming noise background or, alternatively, it can provide high resolution measurements of relatively clean signals over several orders of magnitude and frequency. However, modern instruments offer far more than these two basic functions and this increased capability has led to their acceptance, in many scientific disciplines, as units which can provide the optimum solution to a large range of measurement problems. For example, the modern lock-in amplifier will function as:
* AC Signal Recovery Instrument
It is this versatility, available in a single compact unit, which makes the lock-in amplifier an invaluable addition to any laboratory.
