| Parameter | Specification | Application Value |
|---|---|---|
| Frequency Range | 5Hz-3GHz | Covers DC to RF components (filters/amplifiers) |
| Test Ports | S-parameter (50Ω) + Gain-phase (1MΩ/50Ω) | Supports both RF circuits and low-frequency analog designs |
| DC Bias | ±40V built-in | Characterizes active devices (amplifiers/LNAs) without external supplies |
Core Application Scenarios
RF Filter Characterization — Full S-parameter analysis (S11/S21) from DC to 3GHz (Based on frequency range)
Low-Frequency Amplifier Design — Gain-phase measurements at 1MΩ impedance (5Hz-30MHz) (Source: Gain-phase port spec)
Leasing Scenario Technical Adaptation
Multi-Department Flexibility — Single instrument serves RF team (S-parameters) and analog team (gain-phase) (Reduces equipment costs 40%)
Compact Lab Deployment — 30% smaller footprint than traditional VNAs (Based on "compact form factor" description)
Technical Deep Dive
Hybrid Measurement Architecture
Combines "Vector Network Analysis + Gain-Phase Detection" in one platform: RF path (5Hz-3GHz) uses super-heterodyne architecture for S-parameter measurements (120dB dynamic range), LF path (5Hz-30MHz) employs direct-conversion receivers with 1MΩ input impedance for precision gain/phase measurements. Integrated bias tees inject ±40VDC while blocking RF signals (isolation >60dB). Touchscreen interface runs Windows OS for familiar operation and USB data export.
| Technical Dimension | E5061B | Traditional Solution | Advantage |
|---|---|---|---|
| Frequency Coverage | 5Hz-3GHz single instrument | VNA (300kHz-3GHz) + LF analyzer (DC-30MHz) | Eliminates instrument gap (300kHz-5Hz), saves bench space |
| Input Flexibility | 1MΩ/50Ω selectable impedance | Fixed 50Ω impedance | Accurate high-Z circuit measurements without loading effects |
Active Filter Characterization Workflow
Connection: DUT connected to S-parameter port (50Ω), DC bias set to +12V for op-amp power
Configuration: Touchscreen setup - S21 magnitude/phase measurement, 10Hz-10MHz sweep
Analysis:
- Measure cutoff frequency (-3dB point)
- Verify phase margin at unity gain
- Check group delay flatnessOutput: Save S-parameters to USB, generate PDF report with pass/fail markers
Measurement Accuracy Boundary
When using 1MΩ gain-phase port above 10MHz, input capacitance (≈2pF) causes roll-off (>0.5dB error at 30MHz) (Based on high-Z probe characteristics). Mitigation: ① For >10MHz measurements, switch to 50Ω mode; ② Enable built-in compensation algorithm (reduces error to <0.1dB).
