Keysight (Agilent) E4438C ESG Vector Signal Generator

The Agilent E4438C ESG is a vector signal generator made to work with the newest generation of wireless communication systems. Frequency Range: 250 kHz to 1, 2 3, 4, and 6 GHz, depending on option, with a resolution of 0.01 Hz. Minimum frequency: 100 kHz, however performance is not gauranteed. Standard frequency switching speed with digital modulation on: <35 ms; modulation off: <9 ms. Sweep modes: frequency step, amplitude step and arbitrary list. Dwell time: 1 ms to 60 s with 2 to 401 points. Internal reference oscillator aging rate: <+/-1 ppm/yr. RF reference output frequency: 10 MHz; amplitude: 4 dBm +/-2 dB. RF reference input frequency: 1, 2, 5, 10 MHz +/-10 ppm; amplitude: -3.5 dBm to 20 dBm. Input impedance. Output power range at 250 kHz to 250 MHz: +11 to -136 dBm; >250 MHz to 1 GHz: +13 to -136 dBm; >1 to 3 GHz: +10 to -136 dBm; >3 to 4 GHz: +7 to -136 dBm; >4 to 6 GHz: N/A. Level resolution: 0.02 dB. Pulse modulation on/off ratio: <2.8 GHz: >80 dB; <=2.8 GHz: >64 dB. Rise/fall times: 150 ns. Minimum width with ALC on: 2 microseconds; with ALC off: 0.4 microseconds. Level accuracy: relative to CW at <=4 dBm standard, <=7.5 dBm Option UNB, <=4.5 dBm Option 506) <+/-1 dB. Internal analog modulation source waveforms: sine, square, ramp, triangle, pulse, noise. Rate range for sine waveforms: 0.1 Hz to 100 kHz; square, ramp, triangle: 0.1 Hz to 20 kHz. REsolution: 0.1 Hz. Frequency accuracy: same as RF reference source.

*This is a Web introductory price for one calibration of the Keysight (Agilent) E4438C. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
