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
