The Agilent/Keysight E4406A VSA Transmitter Tester is a vector signal analyzer engineered for comprehensive transmitter testing across 7 MHz to 4 GHz. It delivers spectrum analysis, modulation analysis, and baseband I/Q measurement in a single instrument, supporting digital modulation formats including GSM, EDGE, W-CDMA, cdma2000, 1xEV-DO, HSDPA, and iDEN. Purpose-built for wireless equipment developers and manufacturers, the E4406A combines measurement speed with amplitude accuracy for production-line and design validation environments.
Technical Specifications
RF input spans 7 MHz to 4 GHz with 50 Ω impedance. Absolute amplitude accuracy at 1 GHz reaches ±0.6 dB, with frequency-dependent accuracy of ±1.0 dB (7–1000 MHz), ±1.3 dB (1000–2205 MHz), and ±1.8 dB (2205–4000 MHz). Displayed average noise floor measures -136 dBc/Hz at 1 GHz. Dynamic range (3rd order) at 1 GHz is 102 dB. Resolution bandwidth adjusts from 100 mHz minimum to 3 MHz maximum. RF input power accommodates -2 dBm to -28 dBm with 0–20 dB attenuation and peak carrier power from +30 dBm to –40 dBm.
Baseband I/Q inputs (Option B7C) operate from 5 Hz to 10 MHz with balanced (600 Ω and 1 MΩ) or unbalanced (50 Ω) impedance options. Baseband I or Q individual channels span 5 Hz to 5 MHz with typical noise floor -100 to -110 dBm depending on selected range.
