Catalog Description

Keysight Technologies (formerly Agilent) E8257D-540

250 kHz to 40 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: -20 dBm to +9 dBm with option 1EA to +18 dBm;
Output power: -135 dBm to +7 dBm with option 1E1;
SSB phase noise at 20 kHz offset from carrier -130 dBc to -98 dBc
depending on carrier frequency.
Step/list sweep (8 ms switching typical).

RF output impedance 50 ohms.
Connector type: Precision 2.4 mm male; plus 2.4 - 2.4 mm and
2.4 - 2.9 mm female adaptors.

For rack mount 1CP
See KT-5063-9222 or KT-1CP005A

For rack mount 1CM
See KT-5063-9215 or KT-1CM013A.

For 1CN rack mount
See also KT-E8247C-540 or KT-E8257C-540 for units with modulation.

Option description:
Option 7 is required when using with the  KT-8757D.
Option 8 Removable flash memory provides 2GB of removable compact flash
memory.
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 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 UNU Pulse modulation and is not compatible with UNW.
Option UNW Narrow Pulse Modulation
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 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. No upgrade available for
UNY, must be ordered at time of purchase.
