PSG Series Analog Signal Generator,
Opt.:
521= Frequency range 10MHz-20GHz, ultra high output power;
UNT = AM, FM, Phase Modulation and LF Out
UNW = Narrow Pulse Modulation and
UNX = Ultra-low Phase Noise Performance
The Agilent (now Keysight) E8257D is a fully synthesized signal generator with high output power, low phase noise, and optional ramp sweep capability.
Modulation:
AM, FM, ØM, pulse, and scan
Typical 6 ns rise/fall times and 20 ns pulse width
Dual internal function generators: sine, square, triangular, ramp, and noise
Sweep:
Step, list, and ramp sweep (frequency and power)
Source control using PSA Series Option 215
Agilent 8757D scalar network analyzer code compatible
Automation and communication interface:
10BaseT LAN and GPIB
SCPI and IVI-COM drivers
Backwards compatible with all PSG signal generators
Options:
521 = Frequency range: 10 MHz - 20 GHz, ultra high output power:
Output power: > +30 dBm, +24 to +28 dBm at 250 MHz to 20 GHz; +18 dBm for 10 to 250 MHz; power clamp settable from +15 to +33 dBm
Level accuracy: 500 MHz to 20 GHz: < ±1.0="" db="" for="" -10="" to=""> 20 dBm;
10 to 500 MHz: < ±1.2="" db="" for="" -10="" to=""> 20 dBm with 5-dB step attenuator or harmonic filters
UNT = AM, FM, Phase Modulation, and LF Output:
AM features: Log mode > 40 dB; linear mode > 95 % maximum depth
FM features: 128 MHz maximum deviation
Simultaneously enable AM, FM, ØM, and pulse modulation
Two internal modulation sources
UNW = Narrow Pulse Modulation:
Variable pulse width: 20 ns min.
Variable repetition rate: up to 10 MHz
Rise and fall time: 10 ns
UNX = Ultra Low Phase Noise Performance:
Up to 10 dB improvement compared to standard phase noise performance
Low close to carrier phase noise
Switchable integrated dividers provide a 15 dB phase noise improvement for carrier frequencies below 250 MHz
