FAQ 2010-09-30

External test, 26 TRD LOSS test fails. How do I execute?
In the 26 TRD LOSS test, use 2 m N(m)-N(m) cable for the connection between S and R on the 4291B front panel. If it fails even using the 2m cable, troubleshoot the test station.

*

FAQ 2010-09-08

When utilizing Save/Recall on the E4991A file names are limited to six characters. Is there a method to save/recall files with longer names?

FAQ 2010-07-12

Why isn't calibration option (UK6) available for the 42941A?
The 42941A does not have calibration option because the 4294A specifies total measurement accuracy including the 4294A accuracy.

FAQ 2010-07-12

The marker list function in the NA mode of the 4395A/4396B displays "EXTRA" value in the list below Smith chart. What does this value stand for?
It stands for equivalent capacitance or inductance.

FAQ 2010-07-02

How should I define or select the residual inductance values of Shorting Bars when performing Short compensation on the E4991A or the 4287A?
Nowadays, the authorized standards stipulate the dimensions of shorting devices and the Short Compensation method which uses the defined inductance values of the shorting devices. It is recommended to consider these authorized standards.

FAQ 2010-07-02

Does Sweep End signal output on 24-bit I/O port of the 4294A have similar definition as End of Measure (EOM) signal on LCR meters?
Sweep End signal means the end of entire sweep measurement, not the end of measurement at each sweep point.

FAQ 2010-07-02

What is input impedance of the 4339B?
Nominal input resistance is 1000 Ω .

FAQ 2010-07-02

Can the cylindrical insulator reduce the effect of magnetic coupling between the inductive DUT and the outer conductor of the 16196A/B/C/D fixtures...
Yes, but the effect of reducing the magnetic coupling effect is not sufficient and depends on the DUT.

FAQ 2010-07-02

How should I perform Adapter Setup procedure when using the 16334A with the 4294A?

FAQ 2010-07-02

Can I control the E4980A functions by operation on Web Browser?
Yes, you can control the E4980A over Web Browser by connecting it to your PC by LAN.

FAQ 2010-07-02

E4991A-002/4291A/B-002 with 16454A: Why is impedance measurement value different from the value calculated from permeability?
Error compensation in the permeability measurement firmware produces the difference between measured impedance and permeability.

FAQ 2010-07-02

The 4395A with the 41800A Active Probe or the 41802A 1 MΩ Input Adapter: Is any calculation required for converting the data for 50 Ω input?
No, any conversion calculation related to the difference in input impedance (between 1 MΩs and 50 Ωs) is not required. You can directly read the measurement value on the 4395A.

FAQ 2010-07-02

The 4294A displays a caution "Reduce OSC level" or "Bridge Unbalanced" in Fixture COMP [Short] with 1V OSC level. Is the compensation still valid?
No, the SHORT COMPEN value is invalid. The 4294A cannot measure DUT impedance below 48 ohms at OSC level setting over 500 mV.

FAQ 2010-07-02

The Load correction status displayed on the 4263B LCD doesn't change to ON or OFF in response to the [:SENSe]: CORRection[:STATe] command.
Upgrade the firmware if it's older than Rev 1.05. Otherwise, take the following methods to control the correction mode.

FAQ 2010-07-02

How can I replace the contact tip of the 16334A?
The replacement contact tip is orderable by part number 16334-09002.

FAQ 2010-07-02

How can I connect a test fixture to the measurement terminals of the E4980A when the stopper at the rear of the fixture disturbs the connection?
Remove the stopper from the test fixture by removing a screw at the center of the plastic stopper. Otherwise, remove the front rubber guide from the E4980A.

FAQ 2010-07-02

Why does measurement data exhibit a discontinuity at 5 MHz or 15 MHz and how can the 4294A get rid of this phenomenon?
The 4294A extends its measurement frequency range up to 110 MHz by terminating each measurement terminal with 50 ohm in order to eliminate the resonance of test leads (including leads inside the 4294A).

FAQ 2010-07-02

Error message "PHASE LOCK LOOP UNLOCKED" could be displayed, when the 4294A using an external ref. osc (opt.1D5 or other 10 MHz output) is ON.
The message is removed when any key of the front panel except [Preset]. In this case, the unit works properly.

FAQ 2010-07-02

Why is there a step (discontinuity) on the trace of noise floor around 10 MHz in 4395A's SA mode even when no signal is input into the test port?
This phenomenon is caused by a change in circuit operation of the 4395A at 10 MHz.

FAQ 2010-07-02

How wide range of resistivity can the 4339B measure when used with the 16008B?
The 4339B can measure surface resistivity up to 7 x 1017 Ω and volume resistivity up to 8 x 1018 Ω-cm, but it depends on the electrodes of the 16008B used.

FAQ 2010-07-02
