The Tektronix RSA2200A Series and RSA3300A Series are real-time spectrum analyzers that capture a span of RF frequencies all at one time, seamlessly storing the signal to internal memory. Once captured, a signal can be viewed simultaneously and analyzed in time-correlated frequency, time, and modulation domains. These instruments combine real-time fast-signal capture, internal memory, and modulation analysis with the functionality and operation of a swept spectrum analyzer for looking at very wide spans, all in an integrated, transportable package. The approach captures many signals not viewable on swept spectrum analyzers, letting an engineer characterize a device, system, or signal more completely and rapidly than previously possible.
Listed applications include analog and digital modulation signal quality analysis; understanding frequency and spectral occupancy behavior over time; capture and characterization of undesired, unknown, or interfering signals; and device/system design or operational diagnostic measurement. The series is also applied to getting answers to elusive EMI problems, VCO/synthesizer design, RFID device characterization, general-purpose digital modulation vector signal analysis, spectrum monitoring, and radar measurements. The time-correlated multi-domain view is intended to provide a new level of insight about design or operational problems and possible solutions.
ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we list are equipment we keep on hand. Every pre-owned unit is handled accordingly: pre-owned units are inspected and functionally verified in-house before they ship, while new units ship factory-sealed exactly as received from the manufacturer. That combination of held inventory and in-house verification on used equipment is how we back each order.
The RSA2200A Series and RSA3300A Series are presented together as a price/performance choice spanning four real-time spectrum analyzer models. All share the core real-time approach: a span of RF frequencies is captured seamlessly to internal memory and then analyzed in time-correlated frequency, time, and modulation domains, with swept spectrum analyzer operation available for very wide spans.
Across the family the models differ in frequency range, memory depth, modulation analysis, real-time capture bandwidth, and available triggering modes. The RSA2200A Series provides AM, FM (ASK, FSK), and PM analysis, while the RSA3300A Series adds optional general-purpose digital modulation analysis and the Frequency Mask Trigger. The comparison table below details each model's row.
Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the model whose frequency range, memory depth, and triggering modes match your application, then choose the listing for the condition you need.
The clearest differences are frequency range and starting point. The RSA2203A and RSA2208A cover 10 MHz to 3 GHz and 10 MHz to 8 GHz respectively, while the RSA3303A and RSA3308A cover DC to 3 GHz and DC to 8 GHz. Real-time seamless capture bandwidth is 10 MHz on the RSA2200A Series versus 15 MHz on the RSA3300A Series, and standard memory depth is 512 ksamples on the RSA2200A Series versus 16.384 Msamples (65.536 Msamples with Opt. 02) on the RSA3300A Series.
Triggering and modulation capability also separate the series. The RSA2200A Series offers free run, single, external, and IF Level triggering, while the RSA3300A Series adds Power (Span BW) and Frequency Mask triggering with Opt. 02. General-purpose digital modulation (vector signal) analysis is available only on the RSA3303A and RSA3308A via Opt. 21. Refer to the comparison table that follows for the exact per-model values.
