Can a CalPod system be used with the N1500A software?
No, the CalPod and N1500A Software are not compatible.

FAQ 2016-11-02

Where can I find manuals for discontinued and obsolete Hewlett-Packard, Agilent and Keysight test equipment?
Most Keysight products have PDF manuals that can be found on product pages. Other vendors also supply old manuals.

FAQ 2014-08-01

What resources does Keysight recommend to help facilitate learning proper impedance measurement techniques?

FAQ 2012-07-17

Why is a negative D value sometimes displayed when a furnished PTFE plate is measured with the 16453A?
When resistance value of Short compensation data is too large, measured D value is overcompensated for the Short resistance and results in a negative value

FAQ 2012-04-08

Does the 85070E-020 high temperature probe have a different recommended minimum sample thickness when utilized with different Analyzers?
No. The 85070E option 020 recommended minimum sample thickness is applicable and equivalent for Vector Network Analyzers as well as RF-IV Impedance Analyzers.

FAQ 2012-02-20

Why is permeability measurement result unstable when a low permeability magnetic material or a thin magnetic material is measured with the 16454A?
It is because the impedance of the magnetic material inserted into the 16454A is too low for the impedance analyzer to measure it accurately.

FAQ 2011-06-07

What is the possible cause of the difference when the permittivity measured with the 16453A is different from the value previously obtained?
Most likely cause of the measurement discrepancy or drift is insufficient electrode pressure due to improper pressure adjustment.

FAQ 2011-06-07

Can I have criteria or a list of non-applicable liquid materials for the 16452A?
Avoid measuring acidic, alkaline and ionic materials with the 16452A.

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

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

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

Why is Rp or G measurement value unstable when pure water is measured with the 16452A?
There are two conceivable causes of unstable measurement results. One of primary causes is a change in temperature of pure water sample measured. The other is a slight pollution which resides on the electrode surfaces.

FAQ 2010-07-02

Can the E4991A option 002 measure permittivity or permeability without being used with the 16453A or 16454A?
No. The 16453A or 16454A is required when the E4991A option 002 is used to measure permittivity or permeability.

FAQ 2010-04-29

How should I perform Load compensation when using the 16451B with the 4294A?
Utilize an air-dielectric capacitance of the 16451B's parallel plate electrodes as the load device and perform the load compensation.

FAQ 2010-01-11

What are the frequency limitations on the various probes utilized with the Keysight 85070E Dielectric Probe Kit and why?
The 85070E Dielectric Probe options 020, 030 and 050 have maximum frequeny via the E4991A Impedance Analyzer of 3 GHz.

FAQ 2009-06-26

What is the maximum hydraulic pressure applicable to the 16452A?
Any pressure in excess of 1 atm (atmosphere) should not be applied to the 16452A.

FAQ 2009-01-12

How do I connect the 16048G 1m BNC connector leads to the 16452A?
You need four BNC(m) to BNC(m) adapters (Keysight part number 1250-0216) to connect the 16048G to the 16452A.

FAQ 2009-01-12

Is the collet (center contact) of the 16454A identical to that of the 42942A (part number 1250-0907)?
Yes, When replacing the collet (center contact) of the 16454A, you can use the same part (part number 1250-0907) as that used in the 42942A.

FAQ 2009-01-12

Why is the capacitance measured for a liquid material with the 16452A unstable?

FAQ 2009-01-12

Why is the capacitance measured for an air-dielectric with the 16452A unstable?
If the capacitance measured for an air-dielectric is unstable, check whether the 16452A electrodes are sufficiently clean or not.

FAQ 2009-01-12

There are 4 types of spacers for the 16452A. Is there any criterion for selecting the spacer?
There is no specific criterion for the selection except that the 1.3 mm spacer is required for the short compensation.

FAQ 2009-01-12

Would you give me the information on part number changes for the mechanical parts?
Please refer to the following table.

FAQ 2008-06-29

What is the method of minimizing a measurement data gap at 5 MHz for liquid material measurements using the 16452A?
Since the 16452A is a cell type liquid test fixture which is difficult to connect a load device for Load compensation, the following method is recommended.

FAQ 2008-05-26

Can I use somehow the 16453A for measurements up to 3 GHz?
No, the maximum usable frequency is 1 GHz because measurement uncertainty due to residual impedance of the 16453A rapidly increases at higher frequencies.
