The Advantest R3754 Series is a 150 MHz vector network analyzer designed around the concept of an optimum measurement tool matched to the application. The series covers a signal output range from 10 kHz to 150 MHz with an output power range of +21 dBm to -43 dBm, and was developed to combine high measurement throughput with a wide dynamic range in a single bench-top instrument. The R3754A and R3754B share the same measurement architecture, with the R3754B distinguished by a 6.5-inch color TFT liquid-crystal display and an extended operating temperature range up to +50°C, while the R3754A uses a 5-inch monochrome liquid-crystal display.

The R3754 Series is used for vector measurements of passive and active circuits in the 10 kHz to 150 MHz band. Measurement examples documented for the series include band pass filter characterization (magnitude, phase, group delay), crystal resonator and ceramic oscillator resonance and antiresonance point measurements, crystal resonator impedance measurement, reflection characteristic measurement, and GO/NG limit-line testing of devices under test. The optional Drive Level Measurement (DLD) function (Option 71) is provided for measuring the drive-level dependency of devices such as crystal vibrators at high speed using the Reactance Linear Approximation method, and the Three-terminal Resonator Measurement function (Option 72) is provided for measuring three-terminal resonator characteristics and load capacitance when used with the R17041 measurement fixture.

ValueTronics International, LLC operates from a 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where every pre-owned R3754 Series network analyzer is inspected, functionally verified, and prepared for shipment by our in-house technical team. Unlike pass-through brokers and drop-shippers that list instruments they do not physically hold, we keep this equipment on our floor, which lets us confirm options installed, accessory contents, and operational condition before a quote is issued. Calibration upgrade paths and shipping logistics are coordinated by the same team that performs the verification, so the unit you order is the unit we have inspected.

Brand Heritage

Advantest Corporation is a Japanese test-and-measurement manufacturer that, in the network and component analyzer category, also distributes through ROHDE & SCHWARZ Europe GmbH in the European market, as documented on Advantest's published sales and support office list. The R3754 Series itself remains an Advantest product line.

Compare Other Models in This Series

The R3754 Series consists of two models, R3754A and R3754B, that share the same measurement architecture and signal path. Both cover 10 kHz to 150 MHz, both provide 0.1 Hz frequency resolution, and both offer the same standard measurement modes, sweep types, calibration methods, marker functions, and system interfaces. The difference between the two is found in the display technology and the operating environment they are rated for, not in measurement performance.

Options 10 and 11 expand the receiver from the standard single R input to two-channel (R, A) and three-channel (R, A, B) configurations respectively, and add the OUTPUT2 power-splitter port together with probe-power connectors for FET-probe operation. Options 70, 71, and 72 add time-domain transformation, drive-level dependency measurement, and three-terminal resonator measurement functions. Option 20 substitutes a high-stability time base, and Options 01, 02, and 03 add parallel I/O port hardware in standard, alternate-pinout, and opto-isolated forms.

Each model and option configuration listed in the comparison table that follows is its own product page with pre-owned-matched pricing. If the configuration you need is not listed, contact us — we can usually quote against Advantest's published option list and confirm whether the option set is installed on a unit in inventory.

The R3754A uses a 5-inch monochrome liquid-crystal display and is rated for operation from 0°C to +40°C. The R3754B uses a 6.5-inch color TFT liquid-crystal display, is rated for operation from 0°C to +50°C, and provides backlight ON/OFF control rather than the contrast-only adjustment of the R3754A. Both share the same 640 × 480 dot resolution and the same display modes (rectangular log/linear, polar, Smith with impedance and admittance), so the choice between the two is driven by display preference and the upper end of the lab ambient temperature, not by measurement capability.

Beyond the A versus B distinction, the comparison table identifies the receiver-input expansion offered by Option 10 and Option 11 (which adds the B/R and A/B parameter selections) and the OUTPUT2 power-splitter port that those options bring with them. Time-domain, DLD, and three-terminal resonator capabilities are added through Options 70, 71, and 72 respectively and are visible on a used unit through the soft-key menus they expose.
