E5061B ENA Series Network Analyzer

Procedure overview

• Connect fixture to Gain-Phase test port
• Set measurement parameters
• Perform calibration
• Connect DUT then scale measurement trace
• Perform equivalent circuit analysis

In this demo…

• Impedance measurement (Series-thru method,GP port)
• Calibration at the fixture
• Equivalent Circuit Analysis

Required Instrument and fixture

Instrument

E5061B-3L5/005/720 or E5061BEP-NZA

(E5061BEP-NZA is the package solution which has all

required option for impedance analysis)

1. Connect fixture to Gain-Phase test port

2. Set measurement parameters

Legend: [Key name] = front panel hardware key

 Key name = soft key

 Number = front panel hardware numeric key

a. Press [Preset] then press OK

 Set measurement traces

b. Press [Display] then press Num of traces , and 2

Press Allocate Traces and x2

c. Set measurement parameters

 Press [Meas] the press Impedance analysis menu

 Press Method then press GP Series (T 50 ohm, R 1  Mohm)

 Press |Z|

Press [Trace Next] to select trace2 then press Cs

d. Set Y-axis to log scale for trace1

Press [Trace Next] to select trace1

Press [Scale] then Y-Axis and Log

What is the method under impedance analysis menu?

There are several topologies (or methods) to measure

impedance depending on the DUT’s impedance range.

With the GP Series (T 50 ohm, R 1 Mohm), Series[1]though method at GP (Gain-Phase) port of the E5061B

(port impedance: T: 50 ohm, R: 1 Mohm) is used.

e. Set log sweep parameters

 Press [Sweep Setup] then press Sweep type, and

 Log Freq

 Press [Start] then enter 100 Hz

 Press [Stop] then enter 30 MHz

f. Set IF bandwidth

 Press [Avg] then press IFBW AUTO

 Press IFBW Auto Limit and enter 100 Hz

3. Perform calibration

To measure impedance accurately, recommend to perform calibration. However, if you don’t have calibration kit, you can skip step 3.

a. Select calibration kit

Press [Cal] then press Cal Kit, and Leaded 50 ohm

b. Measure calibration standard

Press [Cal] then press Calibrate

Press Impedance calibration

Make open state then press Open

Make short sate then press Short

Make load state then press Load

c. Activate calibration

 Press Done
