Catalog Description

Keysight Technologies (formerly Agilent) E8257D-520

250 kHz to 20 GHz PSG Analog Signal Generator

The standard PSG is a continuous wave (CW) generator,
You can optionally add analog and/or pulse modulation formats.


Features:
Frequency resolution .001Hz;
10 ms frequency switching speed (typical):
Output power: -20dBm to +15dBm to 20GHz, -20dBm to +20dBM with option 1EU,
-135dBm to +14dBm with 1E1 and +19dBm with options 1E1 and 1EU.

SSB phase noise at 20 kHz offset from carrier -130 dBc to -104 dBc
depending on carrier frequency.
Step/list sweep (8 ms switching typical).


RF output impedance 50 ohms
Connector type: Precision APC-3.5 male, or Type-N with Option 1ED.

The type-N connector is only recommended for use up to 18 GHz.
The standard 3.5 mm(m) RF output connector is recommended for use over the
entire frequency range of Option 520.

See also AT-E8247C-520 or AT-E8257C-520 for units with modulation.


Option description:
Option 7 is required when using with the AT-8757D.
Option 8 Removable flash memory provides 2GB of removable compact flash.
Option 1E1 adds 110dB step attenuator
Option 1EH Improved harmonics below 2 GHz serial numbers less than US/MY4928
Option 2EH Improved harmonics below 2 GHz for units with 1EU and
or serial prefix greater than or equal to US/MY4928
Option 1EA extends typical performance of +23dBm @ 20GHz
Available on serial numbers less than US/MY4928
Option 1EU extends typical performance of +25dBm @ 20GHz
Available on serial numbers greater than or = US/MY4928
Option 1SM Scan modulation, gives deep AM capability, requires option UNT,
replaces option HSM.
Option H30 adds a mixer and coax switch to enable the E8257D to upconvert
the RF signal (input is provided on the rear panel) to a higher
frequency which will be the sum and difference of the RF input
signal and frequency set on the E8257D.
Option HY2 Up to 8 dB improvement in phase noise performance at
offsets > 1 MHz from carrier compared to option UNY.
Lowest phase noise performance with Option HY2 in the
250MHz to 3.2GHz frequency range.
Available at time of purchase only.
HY2 requires 1E1, 1EU and 1EH, not compatible with 1EM
Option UNU Pulse modulation and is not compatible with UNW.
Option UNT provides dual function generators with two independent signals
(Internal1 and internal2) for use with AM, FM, PM, or LF Out.
Waveforms Sine, square, positive ramp, negative ramp, triangle,
gaussian noise, uniform noise, swept sine, dual sine.
Option UNX Ultra-low phase noise performance and is not compatible with UNR
Option UNY is export controlled
Option UNY provides an advanced phase lock loop circuit along with a high-
performance internal frequency reference that improves both the
close-in and pedestal phase stability to provide superior phase
noise performance at all offsets less than 250 kHz from carrier.
With the integrated frequency dividers enabled (included with
Option UNY), the E8257D uses a dividing technique to output carrier
frequencies below 250 MHz. This results in improved phase noise
at all offsets for these frequencies. The dividers can be disabled,
returning the PSG to a standard mode of creating low frequencies
with a heterodyning technique. This mode provides wider deviation
bandwidth for frequency and phase-modulated signals.
