PHILIPS improvements in nuclear instrumentation
These new additions to the Philips range of modular units provide a simple solution for almost any instrumentation problem. Apart f rom the circuitry for their specific function, they include a logic section. Consequently, any required mode of operation can be obtained by merely making the necessary patch connections.
In addition, automatic, pre-programmed operation can be arranged in conjunction with a great variety of peripheral equipment.
Included in the new series of modules are units which convert the measuring results into standardised pulses to operate printers, tape or card punch machines or any other data handling or transmission apparatus. Sole distributors in the U . K . : Research & Control Instruments Ltd., 207 Kings Cross Road, London W.C.1; o v e r s e a s enquiries, please to N.V. Philips' Gloeilampen-fabrieken, Scientific Equipment Dept., Eindhoven, the Netherlands.

SENSITIVITY New <$> Model 130C general purpose 500Kc/s Oscilloscope. Measure high level and low level signals DC to 500Kc /s with one easy-to-use Osci l loscope and without external preamplif iers. Identical vertical and horizontal amplif iers each with sensitivity 200 p v / c m to 20 v / c m . High sensitivity for direct measurement of low level signals from sources such as transducers, strain gauges, sol id state devices, RF detectors, medical and physical equipment. Balanced or single ended input on all sensitivity ranges. Single sweep provided.

UNIT FOR TESTING S E M I
CONDUCTORS $) Model 186A plugs into 185B 1,OOOMc/s Oscilloscope. This new switching t ime tester is for fast, easy analysis of semiconductors. With the new unit installed, 185B osci l loscope has a rise t ime of 0.5ns; displays t ime data such as transistor rise and fall t imes, diode forward switching and reverse recovery t imes and tunnel diode switching time. X-Y Recorder output for permanent records. Model 186A contains Pulse Generator (1ns, 0.1V to 20V), 10mv/cm Amplifier, and two variable Power Suppl ies. Semiconductor plug-in at front panel. Adapter with terminals available for testing external circuit networks. Price Fr. 6815.-Model 187B Dual Trace Amplif ier plug-in unit available for general purpose measurements DC-1,000Mc/s with 4 m v / c m sensitivity.

122A DUAL TRACE
2 0 0 K c OSCILLOSCOPE
Measure or compare two different signals from DC to 200Kc/s. Two vertical amplifiers for easy comparison of related signals such as filter, amplifier and vibration equipment input and output signals. Vertical amplifiers may be used separately to measure two unrelated signals. In many ways, the 122A does the work of two oscil loscopes. Single ended or balanced input, 10mv/cm sensitivity.
120B GENERAL PURPOSE 450Kc OSCILLOSCOPE
Combines simple, easy operation with high quality and accurate performance. Just press beam finder button to see trace, move to centre with position controls and connect signal. Automatic tr iggering provides clear steady signal without difficult adjustment even when input frequency changes. In the absence of input signal, the triggered time base free runs.
• New 50Mc/s Oscilloscope Model 175A. No parallax 6x10 cm display. X axis and Y axis plug-ins for economy and increased flexibility. Delayed sweep facilities. The 175A is now manufactured in Bedford.
