E4438C Vector Signal Generator Overview
Standard Vector Signal Generator Features
Standard Vector Signal Generator Features
• CW output from 250 kHz to 1, 2, 3, 4 or 6 GHz; the high-end frequency is dependent on the frequency
option purchased with your signal generator
• list and step sweep of frequency and amplitude, with multiple trigger sources
• user flatness correction
• automatic leveling control (ALC) on and off modes; power calibration in ALC-off mode is available,
even without power search
• 10 MHz reference oscillator with external output
• GPIB, RS-232, and 10Base-T LAN interfaces
• closed-loop AM
• dc-synthesized FM to 10 MHz rates; maximum deviation depends on the carrier frequency
• phase modulation
• pulse modulation
• a function generator that includes the following features:
—50Ω low frequency output, 0 to 3 V
p
— selectable waveforms: sine, square, ramp, triangle, noise, swept-sine, dual-sine, and pulse
— variable frequency modulation rates
— variable triggering in list and step sweep modes: auto, external, single, or remote
• a pulse generator that includes the following features:
— external pulse
— internal square wave
— internal pulse sources: internal square, internal pulse, external 1 dc-coupled, and external 2
dc-coupled
— adjustable pulse width
— adjustable pulse period
— adjustable pulse rate
• external modulation inputs for AM, FM, ΦM, and I/Q modulation
• simultaneous modulation configurations
