Signal Generator Overview
Signal Generator Models and Features
Option UNX—ultra low phase noise performance
Option UNY—enhanced ultra low phase noise performance
Option UNT—AM, FM, phase modulation, and LF output
• open–loop or closed–loop AM
• dc–synthesized FM to 10 MHz rates; maximum deviation depends on the carrier frequency
• external modulation inputs for AM, FM, and
M
• simultaneous modulation configurations (except: FM with
M or Linear AM with
Exponential AM)
• dual function generators that include the following:
— 50–ohm low–frequency output, 0 to 3 Vp, available through the LF output
— selectable waveforms: sine, dual–sine, swept–sine, triangle, positive ramp, negative ramp,
square, uniform noise, Gaussian noise, and dc
— adjustable frequency modulation rates
— selectable triggering in list and step sweep modes: free run (auto), trigger key (single), bus
(remote), and external
Option UNU—pulse modulation
• internal pulse generator
• external modulation inputs
• selectable pulse modes: internal square, internal free–run, internal triggered, internal doublet,
internal gated, and external pulse; internal triggered, internal doublet, and internal gated
require an external trigger source
• adjustable pulse rate
• adjustable pulse period
• adjustable pulse width (150 ns minimum)
• adjustable pulse delay
• selectable external pulse triggering: positive or negative
Option UNW—narrow pulse modulation
• generate narrow pulses across the operational frequency band of the PSG
• includes all the same functionality as Option UNU
E8267D PSG Vector Signal Generator Features
The E8267D PSG provides the same standard functionality as the E8257D PSG, plus the following:
• internal I/Q modulator
• external analog I/Q inputs
• single–ended and differential analog I/Q outputs
