Keysight Technologies E4990A Spec Sheet
Content is AI-generated. Verify critical details with manufacturer-provided resources.
What frequency range does the Keysight E4990A Impedance Analyzer cover?
The E4990A offers multiple frequency range options depending on the configuration, ranging from 20 Hz up to 120 MHz. The available options include E4990A-010 (20 Hz to 10 MHz), E4990A-020 (20 Hz to 20 MHz), E4990A-030 (20 Hz to 30 MHz), E4990A-050 (20 Hz to 50 MHz), and E4990A-120 (20 Hz to 120 MHz).
What measurement parameters can the E4990A measure?
The E4990A measures a comprehensive set of impedance parameters including |Z|, |Y|, Cp, Cs, Lp, Ls, Rp, Rs (R), D, Q, X, G, B, Complex Z, and Complex Y. It also provides level monitoring for Vac, Iac, Vdc, and Idc. These parameters make it suitable for characterizing capacitors, inductors, resistors, and other passive components.
What terminal configuration does the E4990A use for measurements?
The E4990A uses a four-terminal pair configuration with four BNC (female) connectors on the front panel. The Option 120 model can be converted to a one-port terminal using the 42942A Terminal Adapter (7 mm port) or the 42941A Impedance Probe (SMA(f) port). This four-terminal pair topology eliminates lead impedance and contact resistance errors common in simpler two-terminal setups.
How accurate is the voltage signal level on the E4990A?
The E4990A provides voltage signal levels from 5 mVrms to 1 Vrms with 1 mV resolution. Accuracy at the four-terminal pair port is ±[(10 + 0.05 x f)% + 1 mV] where f is frequency in MHz. The signal level setting accuracy is twice the specified value when operating beyond the 23 ± 5 °C temperature range.
Does the E4990A support DC bias measurements?
Yes, the E4990A features comprehensive DC bias capability. It provides DC voltage bias from 0 to ±40 V with 1 mV resolution and DC current bias from 0 to ±100 mA with 40 uA resolution. The DC bias function includes both constant voltage and constant current modes, plus DC bias monitoring with specified accuracy levels.
What calibration options are available for the E4990A?
The E4990A supports multiple calibration methods including user calibration with user-defined calibration kits (OPEN, SHORT, LOAD), port extension for compensating expanded measurement terminals, and fixture compensation at device contacts using OPEN, SHORT, LOAD standards. Calibration can use either fixed points or user-defined points determined by sweep setups.
What sweep capabilities does the E4990A offer?
The E4990A supports sweeps across frequency, signal voltage, signal current, DC bias voltage, and DC bias current with 2 to 1,601 measurement points. Sweep types include linear frequency, log frequency, oscillator level, and DC bias sweeps. Segment sweep mode allows up to 201 segments with independent settings for frequency range, signal level, DC bias, measurement time, and delay per segment.
What interfaces and connectivity options does the E4990A provide?
The E4990A includes multiple interfaces: GPIB (IEEE-488 compatible), USB host ports for peripherals, USBTMC interface port (USB 2.0 compatible), 10/100/1000 Base T Ethernet LAN, VGA video output for external monitors, and a 36-pin handler interface with TTL-level signals for automated pass/fail sorting. The 10.4 inch color TFT LCD display provides 1024 x 768 (XGA) resolution.
