Keysight (Agilent) E4425B ESG-AP 3000 MHz Analog RF Signal Generator

The Agilent E4425B ESG-AP Analog RF Signal Generator provides all of the features of ESG-A, plus enhanced phase-noise performance. Frequency range: 250 kHz to 3000 MHz, with a 0.01 Hz resolution. Typical switching speed with modulation enabled: <65 ms; with modulation disabled: <55 ms. Sweep Modes: Step: frequency and power, and arbitrary list. Dwell time: 1 ms to 60 sec. Number of points: 2 to 401. Sweep Modes: Step: frequency and power, and arbitrary list. Internal reference oscillator timebase stability: aging rate of <+/- 0.1 ppm per year. Timebase reference output frequency: 10 MHz; output voltage: >0.35 V rms into a 50 Ohm load. External reference input frequencies: 1, 2, 5, 10 MHz +/- 1 ppm; amplitude: >0.15 V rms; input impedance: 50 Ohms. Output power range 250 kHz to 1000 MHz: +13 to -136 dBm (standard), +17 to -136 dBm (option UNB enabled); at >1000 MHz to 3000 MHz: +10 to -136 dBm (standard), +16 to -136 dBm (option UNB enabled). Output power resolution: 0.02 dB. Level accuracy at >2000 MHz to 3000 MHz and +7 to -120 dBm: +/- 0.9 dB; -120 to -127 dBm: +/- 0.9 dB; <-127 dBm: +/- 2.5 dB. Amplitude switching speed: <36 ms typical. Reverse power protection: at >2000 Hz to 4000 MHz: Watts. Max DC voltage: 50 V. SWR: <1.4:1 typical (standard), <1.25:1 typical (option UNB). The E4425B has 5 frequency bands. SSB phase noise at 500 MHz: <–138 dBc/Hz; at 1000 MHz: <–134 dBc/Hz; at 2000 MHz: <-127 dBc/Hz; at 3000 MHz: <-124 dBc/Hz. Frequency modulation maximum deviation: N x 1 MHz. Modulation frequency response on FM1 in a 1 dB bandwidth: 20 Hz to 100 kHz; in a 3 dB bandwidth: 5 Hz to 10 MHz. On FM2 in a 1 db bandwidth: same as FM1; in a 3 dB bandwidth: 5 Hz to 1 MHz. Phase modulation maximum deviation in normal bandwidth: N x 10 rad; high bandwidth: N x 1 rad, with a resolution of 0.1% of set deviation. Modulation frequency response in normal bandwidth: dc –100 kHz in mode 1, dc –100 kHz in mode 2; in high bandwidth: dc –1 MHz in mode 1, dc –1 MHz (typ.) in mode 2. Amplitude modulation range: (envelope peak = max. specified power): 0 to 100% with a resolution of 0.1%. Rate: 10 Hz to 10 kHz. Accuracy (1 kHz rate): <+/-(6% of modulation index setting + 1%).

dBm
dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave
Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
