Tektronix -- 7L5
Spectrum analyzer

The 7L5 is a 5 MHz spectrum analyzer with digital storage. Frequency stability is within 5 Hz/hr and center frequency (dot) can be read with six digit accuracy immediately after turn-on. There is no need to fine tune the display. Complex measurements and analysis can be made with relative ease. Built-in micro-processing circuits decode control settings, process frequency and reference level information, and optimize sweep time and resolution for the selected frequency span. The 7L5 with ...

Fluke -- 190B
ScopeMeter

Series: Speed, performance and analysis power For demanding applications, the ScopeMeter 190C and 190B Series high-performance oscilloscopes offer specifications usually found on top-end bench instruments. With up to 200 MHz bandwidth, 2.5 GS/s real time sampling and a deep memory of 27,500 points per input, they’re ideal for engineers who need the full capabilities of a high-performance scope in a handheld, battery powered instrument. • Dual input - 200, 100 or 60 MHz bandwid ...

AVO -- THE “AVO” VALVE CHARACTERISTIC METER
Valve characteristic meter

'The problem of designing a Valve Testing Instrument capable of giving a true and comprehensive picture of the state of any valve, has always been one of considerable magnitude, increasing in complexity as new valve types are brought into general use. For a quick general purpose test necessitating a minimum of time and technical effort a mutual conductance figure will give an adequate idea of a valve’s usefulness, and the original “ AVO ” Valve Tester was designed to test the ...

Marconi -- 2031
Generator

The 2030 series Signal Generators cover the frequency ranges 10 kHz to 5.4 GHz with three models: 2030 (10 kHz to 1.35 GHz), 2031 (10 kHz to 2.7 GHz) and 2032 (10 kHz to 5.4 GHz). A dot matrix display with soft key selected screen options allow flexibility of operation and ease of use. The output may be amplitude, phase, or frequency modulated with pulse modulation available as an option. Modulation is available using a combination of up to two external signal inputs and a built-in LF so ...

Schlumberger -- 7045
Digital multimeter

The 7045 is essentially a voltage measuring device. Where necessary, multimeter inputs must be converted into a dc voltage level and suitably scaled prior to analogue to digital conversion. This process is carried out in the Signal Conditioning Section. The Analogue to Digital (A-to-D) Converter produces two balanced pulse trains at its output. Any measured input causes the pulse width of one of the trains to increase, with a proportionate decrease in the width of the other; the n ...
