Lambda Photometrics Ltd

Lambda Photometrics are a long established supplier of scientific equipment to the UK photonics and Test & measurement industry.

As UK representatives for Stanford Research Systems, we are pleased to supply and give local support for the following products of interest to the audio community.

SR1 Audio Analyser: provides high-end measurement performance and capabilities (comparable to the AP2700 series), but at a fraction of the cost of the competition. Full dual domain analysis functionality (analogue & digitial), -110dB THD+N (1kHz, 2V, 22kHz B/W), +/-0.008dB flatness, 200kHz system bandwidth. Fully integrated PC and extensive connectivity (Ethernet, RS232, GPIB, USB).

FS725 Rubidium Frequency Source: a highly accurate and stable "atomic" frequency reference. Us of this product to act as a master clock in an audio/video system can dramatically improve performance. Available at a fraction of the cost of established pro-audio master clocks (e.g. Antelope 10M).

SR10 & SR11 Audio Switchers: low crosstalk (-155dB @ 20kHz) audio switchers to allow automated measurement in multichannel applications. Up to 16 units can be cascaded, with full Ethernet RS232 & GPIB connectivity. Seamless integration to the SR1 Audio analyser for multichannel testing.

DS360 Low Distortion Function Generator: Up to 200kHz of low distortion (<-100dBc) sine, square white and pink noise output signals. Frequency accuracy is 0.0025%, and sweeps and bursts are available. Analogue outputs plus AES-EBU and SPDIF/EIAJ digital outputs.

FS730 & FS735: series of distribution amplifiers configured for 10MHz or 5MHz (master clock signals), CMOS logic, broadband 50 Ohm or 75 Ohm applications.

Please contact us for Europe based sales, technical and service support. We have fully equipped service labs, and demo stock available for you to evaluate.
