This might be one of the first advertisements for Rohde & Schwarz (R&S) test and measurement (T&M) products to appear in a U.S. publication (December 13, 1965 Electronics). A brief search for earlier instances did not turn up anything prior to 1965. Please contact me if you have seen one. R&S, as you probably know already, is now a major player in the communications T&M world. Hewlett Packard (HP) of course was one of the largest - if not the largest - maker of spectrum analyzers, network analyzers, noise figure test sets, modulation generators and analyzers, signal generators, o-scopes, etc., up through about the 1980s - maybe into the 1990s. Once the cellular and wireless everything markets took off, Rohde & Schwartz test equipment (TE) began appearing on lab test benches more and more frequently. Engineers and technicians quickly learned to appreciate the new advanced features that older industry stalwarts were slow to adopt and incorporate. Then, in the early 2000s, HP decided to divest its TE market into a new company with a weird, totally unfamiliar name, leaving a lot of customers with strong brand loyalty feeling abandoned (gotta admit I was one of them). The switch to other brands was made much easier from then on, and, at least where I worked at the time, labs and production test areas began mutating in color from gray to light blue.

Get the extra capability, greater reliability, and longer useful life of Rohde & Schwarz!

Since 1933, Rohde & Schwarz' group of unusually creative engineers have been designing electronic instruments that are truly unique. These instruments are constantly ahead of what is considered to be the state-of-the-art. They are more precise. They are easier to use and read. Many perform extra functions. Some do jobs never done before. All are constructed with uncompromising quality - drastically reducing maintenance requirements. As a result, they do not become obsolete as fast as ordinary instruments - they provide more years of useful life. As you might expect, you pay a little more initially for some of these - but an Investment in Rohde & Schwarz saves you plenty in the long run!

Type ZRZ

Now! Read reflection coefficients and attenuations directly!

The Rohde & Schwarz Type ZRZ Reflectometer is a modern, accurate, and dependable instrument for measuring reflection coefficients from 0.5% to 100%, and attenuations from 0.05 dB to 5 dB. Read-out is direct and instantaneous from the built-in scale; no calculations or interpolations are required. Outputs for a slave meter and a recorder increase the unit's versatility, and its low test voltage makes it ideally suitable for semiconductor circuits.

Additional Features:

• Frequency range 30-1000 MHz

• Broad-band, no tuning required

• Signal generator is only external accessory required

• Automatic voltage control, signal generator voltage can vary by factor 2:1

• Fully transistorized

An ideal RF Power Generator for use with Slotted Lines and other measuring instruments! This Rohde & Schwarz VHF Power Signal Generator features seven subranges, covering from 25 to 480 MHz. Typical power output is between 500 and 800 milliwatts which can be attenuated as much as 40 dB when required. Each range has its own scale, calibrated directly in frequency.

Type SLSV

Features:

• Frequency calibration accuracy ±1 %

• Frequency drift less than 5 parts in 10⁵ within 15 minutes after 2 hours of operation

• Switch selected square wave modulation

Here's a multi-purpose receiver for monitoring radio reception, and interference, and making lab measurements. It's a complete transmission test set, using a built-in tracking generator with 30 mv fixed output. It combines a selective microvoltmeter with RF preselection. And it covers 25 to 900 MHz with just 3 plug-in RF units. AC and battery operation.

Other Features:

• Measuring range 0 to 120 dB referred to 1μV

• Narrow (±12 1/2 kHz) and wide (±60 kHz) bandwidths

• Has built-in tracking calibrating oscillator, eliminating need for calibration charts

• Accuracy is ±1.5 dB

• Linear (20 dB) and logarithmic (4G and 60 dB) scales

• Indicates RMS, quasi-peak, and peak values (with slide-back voltmeter)

• Provides AM and FM demodulation

Monitor VHF and UHF with One Receiver! Covers 25 to 900 MHz!
