The R3754 Series is an Advantest network analyzer with its measurement frequency range set to 10 kHz to 150 MHz. It is built for adjustment and test in the production and inspection processes of crystal, ceramic, LC, and sensor parts, pairing enhanced functional performance with a low price point. Two display types are offered: the R3754A with a 5-inch monochrome LCD and the R3754B with a 6.5-inch color TFT LCD.
Within the crystal device manufacturing process, the series supports pre-process measurements such as blank selection and frequency adjustment, along with equivalent circuit constant analysis. In the ceramic device manufacturing process it handles frequency selection of the ceramic base, direct filter analysis at resonant and anti-resonant points, and filter/resonator spurious measurement. Advantest recommends the R3754A for the pre-process and the R3754B for shipment inspection and receiving inspection.
ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house against the original manufacturer specifications before it ships, while new units leave factory-sealed exactly as received. That combination lets buyers source this instrument with confidence in its condition and availability.
Advantest Corporation traces its roots to Takeda Riken, the test-equipment maker that adopted the Advantest name in 1985. The instrument brand has carried that name consistently since.
The R3754 Series comprises two main-unit models that share the same network-analyzer architecture, frequency range, and basic performance, differing in their display unit. The R3754A uses a 5-inch STN monochrome LCD and the R3754B uses a 6.5-inch color TFT LCD, both at 640 x 640 dots.
Advantest positions the two display variants by process stage: the R3754A is recommended for the pre-process, while the color R3754B is recommended for shipment inspection and receiving inspection where on-screen color coding aids clarity. Both models accept the same input-channel and function options.
Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the model and channel configuration that fits your application, and the linked page reflects current availability and pricing for that exact unit.
The primary difference between the two models is the display: the R3754A ships with a 5-inch STN monochrome LCD (with contrast control and backlight on/off), and the R3754B ships with a 6.5-inch color TFT LCD supporting 256-color user editing. Core measurement performance such as the 127 dB dynamic range, 0.05 ms/point sweep, and 10 kHz to 150 MHz range is common to both.
Input channel count is set by option rather than by model: a single channel is standard, Option 10 adds a second channel, and Option 11 provides three channels for 2-device simultaneous measurement. Function options including RLA drive level measurement (Option 71), TDR (Option 70), and 3-terminal resonator measurement (Option 72) apply across the family. See the comparison table for the per-model and per-option breakdown.

Important: Input destruction level: +24 dBm, ±3 VDC.
Important: The operating manual is optional and is not included with the main unit (select Option 90 Japanese manual or Option 91 English manual separately).
Important: With a measurement range setting which includes 32.5 MHz, absolute measured phase characteristic values are not guaranteed. They are guaranteed when the unit is used with a measurement range setting between 10 kHz and 32.5 MHz, or between 32.5 MHz and 150 MHz.
Important: The 3-terminal resonator measurement function (Option 72) requires the R1704 and a CAL Kit. The R17041 test fixture and calibration kit are optional and ordered separately.
Important: Additional input channels are optional: the standard unit provides one input channel; 2-channel input is Option 10 and 3-channel input is Option 11.
Important: The 2-channel/4-trace simultaneous (2-device) measurement function requires the 3-channel input model (Option 11).
Recommended pairing: use the R17041 fixture (test fixture and switch box) for 3-port resonator measurement, which also calls for the R1704 and CAL kit under Option 72.
