FAQ 2010-09-19

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 2010-09-19

4263B: What is the signal source output impedance?
*

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 4339B with 16339A test fixture: The insulation resistance of a high value ceramic C (≥1000 pF) is very noisy even after 60 sec. charging time.

FAQ 2010-07-02

What is the 4294A's GPIB command to read sweep frequency data though OUTPDATA command transfers only measurement data?
"OUTPSWPRM" or "OUTPSWPRMP" are the commands to read out the sweep parameters according to the number of points.

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 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

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

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 can I get DC bias current resolution of 20 mA in the 1 A to 2 A range when the E4980A-002 is used with 2 units of the 42841A?
The bias current resolution has been improved on the E4980A with firmware revision 2.12 and above. If your E4980A has firmware revision 2.10 or below, upgrade the firmware to revision 2.12 or above.

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 the DC resistance measurement function of the 4287A require to be calibrated at the same time with Open/Short/Load calibration?
The specified accuracy for the DC resistance measurement is applied when the Open/Short/Load calibration for the DC resistance measurement is performed.

FAQ 2010-07-02

In the 4395A/4396B NA mode, the "dB" expression is used instead of the "dBm" even when the meas. parameter is set to absolute power amplitude.
Please regard the displayed "dB" as "dBm".

FAQ 2010-07-02

Do the coaxial Short and 50 Ω Load terminations for the 42941A have accuracy specifications?
No, both the coaxial Short and 50 Ω Load standard terminations for the 42941A do not have accuracy specifications.

FAQ 2010-07-02

The E4980A/4284A display much lower resistance values than DUT's DC resistance when measuring high-value resistors in Mega-ohms region.
Set the measurement function to Cp - Rp mode to measure high resistance properly.

FAQ 2010-07-02

Can 4263B preserve Open/Short/Load correction data by using Save/Recall function?
No.

FAQ 2010-07-02

The 16085B 4-Terminal Pair to 7 mm (APC-7) adapter: Is it advisable to use fixture compensation standards or coaxial calibration standards?

FAQ 2010-07-02

Can I separately order the heat-resistant cable without ordering E4991U-007 Upgrade Kit?
No. The heat-resistant cable cannot be ordered separately from the E4991U-007.

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

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

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

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

Why cannot I control TEST SET ATTEN PT1 and PT2 functions in ATTENUATOR MENU when the 87511A S-parameter test set is used with the 4395A?
The TEST SET ATTEN PT1 and TEST SET ATTEN PT2 functions cannot be controlled because the 87511A is not equipped with input attenuators.
