Rohde & Schwarz Questions I Actually Get as the Person Who Buys Test Equipment

I’m the person at our company who handles purchasing for our engineering team. Not an RF engineer, not a procurement director—just the one who makes sure quotes come in, orders ship, and invoices don’t get rejected by finance. Over the years I’ve placed my fair share of test equipment orders, including some from Rohde & Schwarz. These are the questions I keep hearing from people who are trying to figure out whether R&S is worth the hassle for a smaller company.

Wait, is Rohde & Schwarz the TV company?

No. And I get why people ask—I had the same confusion when I first started ordering. Rohde & Schwarz is a German electronics group based in Munich. They make test and measurement equipment, broadcast systems, cybersecurity stuff, and communications gear. They do not make televisions.

The TV brand people are thinking of is probably RCA or maybe a private-label TV sold under some similar-sounding name. I honestly had to triple-check this myself once. So when someone asks me “where are TVs made?” because they saw “Rohde & Schwarz” on a purchase order, I have to explain: that’s not what this company does.

The group is big—over 13,000 employees worldwide—and you’ll see them in aerospace, defense, automotive, and wireless testing. But TVs? No. Not part of the portfolio.

I run a small company. Will they even take my order seriously?

This is the fear I hear most. The way I see it, people assume a German engineering giant only wants million-dollar defense contracts and doesn’t have time for a small firmware shop that needs one signal generator.

To be fair, some large test equipment vendors can be a bit dismissive when you’re only buying one box. But in my experience, Rohde & Schwarz treats small orders fine. I’ve placed orders under $1,000 with them and they didn’t make me feel like a nuisance. Maybe it helped that I had a clear part number and shipping address. But honestly, their admin side was no worse than any other vendor I deal with.

The bigger issue is the opposite: they don’t always chase you. If you’re a small customer, you might need to be the proactive one. That’s fine. I’d rather have a vendor that doesn’t blow up my inbox than one that calls me three times a day.

Look, I started our vendor relationships with small test orders. The vendors who took those $200 orders seriously are the ones I still call for $20,000 orders. That principle applies to Rohde & Schwarz too. Just be ready to ask specific questions.

Which Rohde & Schwarz signal generator should I buy?

This is the “what’s the right one?” question that has no clean answer, and it drives engineers crazy. I’ve seen people freeze trying to decide between a used SMB100A and a new SMC100B. Here’s what I’ve learned from watching our RF folks work with these:

• SMB100A — a classic, reliable RF signal generator up to 40 GHz depending on the option set. We bought a used one and it’s still doing fine.
• SMC100A / SMC100B — entry-level, lower cost, good for basic CW signals and simple modulation. Fine for many labs, not great if you need very low phase noise.
• SMW200A — the big one. Overkill for most small companies unless you’re testing 5G or radar stuff.

The decision usually comes down to: what frequency range do you actually need, and do you need pulse modulation? Don’t overbuy. I’m not 100% sure about all the model variations that exist right now, but the SMB100A still shows up frequently in test labs for a reason. It’s proven.

If you’re just starting, look at the used market. But verify that the calibration is current. The cost of calibration can exceed the purchase price on old units—that’s the hidden gotcha nobody mentions.

Is the FSH3 spectrum analyzer still worth buying used?

Ah, the Rohde & Schwarz FSH3. This is one of those products that keeps coming up because people find old listings and wonder if it’s a bargain.

The FSH3 is a handheld spectrum analyzer, originally introduced around 2003 or so. It covers 100 kHz to 3 GHz. Compared to modern analyzers, it’s limited: no big touchscreen, no modern FFT features, relatively slow sweep. That said, it’s built like a tank. I’ve seen used ones with dents and scratches that still measure fine.

Here’s the thing: buying an FSH3 today makes sense only if:

• You need a field-unit for basic RF measurements
• Your budget is very tight
• You can find one with a valid calibration certificate

But if you need modern features like wideband signal analysis or spectrum emission mask testing, an FSH3 will drive you crazy. Don’t oversimplify the decision by just comparing frequency range. The user interface alone matters more than the spec sheet.

From my perspective, the FSH3 is a reasonable starter instrument for measuring basic signal levels and harmonics. But don’t treat it as a substitute for a lab-grade analyzer. We ended up using our FSH3 mostly as a portable troubleshooting tool, not a primary instrument.

How do I actually reach Rohde & Schwarz by phone?

This frustrates people because the company is global and the phone numbers on the website depend on your region. The short answer: go to rohde-schwarz.com, find your local Rohde & Schwarz contact page, and look for the sales office near you. There isn’t one single toll-free number for the whole company. I tried that once. It doesn’t work.

In the U.S., for example, you can search “Rohde & Schwarz USA contact” and you’ll get their Columbia, Maryland headquarters number. But if you call that number and ask about, say, a spectrum analyzer repair, they’ll probably route you to a service center. It’s not always fast.

My trick: call during business hours and ask for “aptest applications.” That tends to get you to someone who actually knows the products. Also, if you already have a quote or a purchase order number, have it ready. The admin people on the other end are friendly, but they can’t help you without a reference number.

And don’t ask for “Rohde” or “Schwarz” as if they’re two separate people. I made that mistake once. Yeah. It’s one company. One long hyphenated name.

What about calibration, repair, and lead times?

Here’s the part that surprises people: calibration and repair turnaround times are not always quick. I’ve had a signal generator out for calibration that took three weeks. To be fair, that was partly because shipping to a service center and back adds days.

For a small company, that downtime matters. If you don’t have a backup instrument, you’re stuck. So my advice is to ask about service turnaround before you buy, not after. And check whether the instrument you’re buying comes with an initial calibration certificate. Most do, but confirm.

There’s something satisfying about opening a brand-new Rohde & Schwarz box—the manuals, the torque wrench, the calibration data. But that satisfaction fades fast if the unit sits in receiving for a week because finance wants to verify the repair order. (Ugh, that happened to us once.)

If you’re juggling a used FSH3 or an older SMB100A, ask the seller for a copy of the calibration certificate before you commit. That single document can save you from a $1,500 surprise.

Should I buy new or used?

I went back and forth on this one myself for nearly two weeks when we needed a spectrum analyzer. A used FSH3 was half the price of a new one. But the used unit had no warranty, no support, and I couldn’t verify calibration easily.

The numbers said “buy used.” My gut said “not this time.” I went with my gut. Turns out that was the right call: we needed newer EMC features for a client requirement later that year. The new unit paid for itself in project credibility.

Do I think you should always buy new? No. I’ve bought plenty of used R&S gear. But I’ve learned to only buy used if you can verify the calibration status and you’re confident about the model’s limitations.

Take this with a grain of salt: I’m not an RF engineer. I’m the buyer who has to make sure the gear actually arrives, works, and doesn’t cause accounting headaches. But after enough orders, you start to learn what questions matter.

The bottom line: Rohde & Schwarz is a serious test equipment group that doesn’t make TVs. They can be a great partner for small companies, but you need to be specific about what you need and ask about calibration, lead times, and support before you commit. Start small. Verify everything. And yes, the name is impossible to type without hyphenating.
