Advantest R3671 Signal Analyzers

DESCRIPTION

The R3671 and R3681 are one of these new measuring instruments for this new era of test and measurement requirements. The R3671 and R3681 are high performance signal analyzers. Employing our unique RF technology, the R3671 and R3681 achieve an Average Display Noise Level of –158 dBm*1), a Third-Order Intercept Point (TOI) specification of +26 dBm*2), and a signal purity of –122 dBc/Hz*3) to enable measurements over a wide dynamic range. The R3671 and R3681 also have unique noise correction functions that enhances their dynamic range (–84 dBc [typical]) for W-CDMA adjacent leakage power (ACLP) measurements.

Dynamic range measurement

By making full use of the latest RF techniques, the R3671 and R3681 enable measurement over a wide dynamic range:

● Average Display Noise Level: –158 dBm typ. (RBW=1 Hz, @ 1 GHz) Built-in Preamplifier On: –168 dBm typ. (RBW=1 Hz, @ 1 GHz) 

● 1 dB Compression Point: +10 dBm typ. (@ 200 MHz to 3.5 GHz) 

● Third-Order Intercept Point (TOI): +26 dBm typ. (@ 2 to 3.5 GHz) 

● Built-in Attenuator: 5 dB steps 

● Resolution Bandwidth (RBW): 1 Hz to 10 MHz (Sequences 1, 2, 3, and 5) 

● Dynamic Display Range: 10 div. fixed 0.1 to 1 dB/div. (0.1 dB steps) 1 to 20 dB/div. (1 dB steps) 

● Steep Shape Factor Approximately 3 times the conventional value. This greatly narrows the carrier near-field measurement resolution.

Highly Accurate Measurement

The R3671 and 3681 provide highly accurate measurement by adopting high-performance digital IF technology. 

● General Level Accuracy: >±0.73 dB (50 MHz to 2.5 GHz, 10 dB ATT, 100 kHz RBW) 

● Level Display Linearity: Inaccuracy reduced 

● Level Display Stability: Instability significantly improved 

● Self-calibration: Calibration time shortened
