Lambda Photometrics are proud to release the latest generation of VeriSens vision sensors from Baumer who sets new standards of operating simplicity and dependability.

Three new ranges of VeriSens® provide optimal solutions for various applications in automation systems.

The ID Series vision sensors reliably solve industrial identification and imprint control tasks. The VeriSens® ID-100 reads all standard 1D/2D and GS1 codes and is therefore ideally suitable for controlling production sequences. The VeriSens® ID-110 additionally enables text and date parameters to be checked for correctness and legibility (OCR/OCV). Check & Sort tasks for quality control purposes are particularly easy to solve with the VeriSens® CS-100 of the CS Series. For example, it provides 5 digital outputs which enables it to check components for various characteristics and sort them directly without external PLC requirements.

The new FEXLoc® technology guarantees reliable 360° position tracking of variable component positions.

The XF Series has the high performance of a vision system but is as easy to use as a vision sensor. The extensive functions of the VeriSens® XF-100 and XF-200 make it possible, for instance, to validate component geometries, locate parts or check the form, content and correct labelling of packaging.

All VeriSens® vision sensors of the new generation are integrated into an industrially robust metal housing of the IP 67 protection class and achieve high production rates by performing up to 3000 evaluations per minute. The uniform, intuitive operating software and extremely simple integration of the new VeriSens® series permit flexible operation during changing requirements and applications.

We are proud to announce the launch of a new 8-channel digital delay/pulse generator, the DG645 from Stanford Research Systems, now available in the UK from Lambda Photometrics.

The DG645 digital delay/pulse generator is an improved version of its predecessor, the DG535 with <25ps rms jitter, up to 10MHz repetition rate, higher accuracy and with more channels.  

The front panel has five outputs, T0 and four independent pulses (AB, CD, EF, GH). The programmed delays can be set between 0 and 2000 seconds, with 5ps resolution, to control the timing of the leading and trailing edges of the four output pulses. There are three optional delay output configurations to choose from, and each configuration has eight delay channels with 5V, 30V or combinatorial outputs.

The DG645 can be triggered internally or externally. The internal rate generator can be set from 100µHz to 10MHz with 1µHz resolution. An external trigger input can trigger a timing cycle, a burst of cycles or a single shot. A trigger inhibit input is included as standard which can disable the trigger or any of the pulse outputs during a timing cycle.

Ovenized crystal and Rubidium timebases are available as an option if higher stability is required. GPIB, RS232 and Ethernet interfaces are included as standard, allowing remote control for all instrument functions.

Available in the UK from Lambda Photometrics Ltd; the Stanford Research PRS10 is a 10MHz Rubidium (Rb) disciplined frequency source with ultra-low phase noise, excellent stability and low aging rate. It is an ideal component for use in any OEM or end-use application requiring a stable precision low noise frequency standard.

Key Features:

• 10MHz output
• Very low phase noise (<-130dBc/Hz at 10Hz)
• Time tags or phase-locks to a 1pps input
• 72 hour Stratum 1 level holdover
• RS-232 interface for diagnostics, control and calibration
• Optional break-out connector board

The SR1 Dual-Domain Audio Analyzer is a stand-alone instrument that delivers cutting edge performance in a wide variety of audio measurements.

SR1 uses an integrated computer running the Windows XP embedded operating system, so operation will be immediately familiar and intuitive.

Depending on the application, SR1 can be operated with an external mouse and keyboard, or by using the front-panel knob, keypad and touchpad.  

At the heart of SR1 is a uniquely flexible analog signal generator. All of the standard audio waveforms are available including sine, synchronous burst sine, noise (white, pink, and filtered), standard intermodulation test signals (SMPTE, CCIF, DIM), square waves, arbitrary waveforms (ASCII and .WAV), ramps and multitone waveforms. Many of these signals can be combined in the generator allowing you to create an unlimited number of test waveforms. 

• = -108 dB THD+N (analog system at 1 kHz, 20 kHz BW)
• 200 kHz (signal generation & measurements including FFTs)
• = -114 dBu analog analyzer noise ( 20 kHz BW)
• ± 0.008 dB flatness (analog system, 20 Hz to 20 kHz)
• Low Crosstalk (= -140 dB analog inputs)
• = 800 ps jitter (700 Hz to 100 kHz)
• Dual-Channel FFTs  

The same flexibility and performance is found in SR1’s digital audio signal generator. Almost all the same waveforms found in the analog generator are available in the digital generator with the addition of several special digital test waveforms including digital constant, walking bits, and a staircase waveform (for D/A testing).

SR1 provides a complete set of measurements for digital interface testing. Carrier level and sampling frequency are measured directly. Status bits are fully decoded in both professional and consumer formats, and user bits are displayed as well.

SR1’s Jitter Analyzer measures jitter in both the time and frequency domain, including continuously variable bandwidth limiting and weighting in both domains. For frequency domain measurements, live zoomable and heterodyned spectral displays of jitter are available. With a residual jitter of only 800 ps, the performance of SR1’s jitter analyzer is unbeatable.
