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 magazine). 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 (Agilent,
now weirdly named Keysight), 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. Since this was first posted, a guy wrote to
tell me he found a few pieces of
brand new R&S test equipment in the attic of an old house in Germany (none
of the models in this ad). I put him in touch with Rhode & Schwarz corporate to
see whether they would be interested in purchasing it for its historical value.
I never did hear back from him.
Rohde & Schwarz Ad
 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!
