How is measurement accuracy of the E4980A specified when ALC function is set to ON?
Find the test signal level setting in ALC Off mode where the applied signal voltage or current across the DUT is equal to ALC setting value. Then calculate accuracy at this test signal level setting as follows:

FAQ 2008-06-11

Does the 4338B carry CE mark?
Yes, the 4338B carries the CE mark.

FAQ 2008-06-11

Is Insulation Resistance calibration data included in the calibration report on the 16380A?
No, insulation resistance for the 16380A is not included in the calibration report because it is unspecified.

FAQ 2008-05-20

Do the 42090A and 42091A have calibration data?
No, both the 42090A and 42091A do not have calibration data because these terminations are absolute reference devices to define 0 S and 0 Ω respectively.

FAQ 2008-05-20

What are significant error sources when a thin film material is measured with the 16451B?
Small air gaps become primary error source for the permittivity measurement of thin materials.

FAQ 2008-05-20

Can the 16453A measure film materials thinner than 0.3 mm?
Measurement error due to air-gap significantly increases for thinner MUTs than 0.3 mm. Pre-forming electrodes on both sides of MUT can reduce the error.

FAQ 2008-05-20

What is the electrical length value defined for the 16454A?
The electrical length of the 16454A has been preset to the E4991A as 0 mm.

FAQ 2008-05-20

Why is it recommended to pre-form electrodes on both sides of thin film materials measured with the 16451B?
Pre-forming electrodes on both sides of film materials can minimize measurement errors due to air gaps between 16451B's electrodes and the material.

FAQ 2008-05-20

Why don't the 42030A have high frequency calibration values for 1 Ω and lower resistance standards?
Resistance standards below 10 Ω do not require high frequency calibration values because these resistors are only used at 1 kHz or DC.

FAQ 2008-05-20

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.

FAQ 2008-05-20

What are the size, cable length and weight of the 42941A probe?
The 42941A has 15 cm long probe body, 1.5 m long cable and approximately 2.4 kg in weight.

FAQ 2008-05-20

How large power can be applied to individual standard resistors of the 42030A?
It is recommended that the applied test signal level is less than 0.1 W. For resistors below 1 Ω, test current should be less than 0.5 A rms.

FAQ 2008-05-20

Why cannot I measure well DUTs above 100 G ohm with the 16117B?
Since the 16117B has non-shielded clips, the maximum measurable range is limited to 100 G ohm.

FAQ 2008-05-19

Why are the networks disconnected on certain actions regarding the MCF file?
To avoid inconsistent software behavior, the networks are disconnected automatically before the MCF is reloaded or a reference MCF is saved...

FAQ 2008-01-29

How to upgrade from 1 to 2 channels
It is not possible to upgrade a 1 channel version to a 2 channel version. You have to decide from the beginning how many channels you need.

FAQ 2008-01-29

What is a crest factor?
The crest factor defines the ratio between Vp to RMS. The ideal sine wave for example has a crest factor of 1.414. Any crest factor higher than 1.414 shows additional noise, distortion or spikes. In addition the crest factor shows signal boundar...

FAQ 2008-01-29

What is the expected lifetime of the relays used in the Keysight 34970A plug-in modules?
The Keysight 34970A Relay Maintenance System automatically counts the cycles on each relay in the instrument and stores the total count in non-volatile memory on each switch module.

FAQ 2008-01-08

Does the x6000 Automated X-ray Inspection system have a new X-ray tube?
The x6000 Automated X-ray Inspection System uses the same, high quality, closed tube used in the 5DX. This closed tube provides a long life to our customers.

FAQ 2007-12-05

我在使用是德阻抗分析仪测量电容器时,Q和D出现了负值,我该如何处理呢?
对于低损耗器件(高Q、低D)来说,在LCR表/阻抗分析仪上通常不会出现负读数。请注意负读数在物理上是不可能的(对于无源元件),下面的内容解释了出现负读数的原因。

FAQ 2007-11-18

What is the maximum board thickness and can it be increased?
The maximum board thickness on the x6000 Automated X-ray Inspection System is 125mils and it cannot be increased.

FAQ 2007-04-22

What is the X-ray radiation dosage relative to the 5DX?
The x6000 Automated X-ray Inspection System radiation dosage is about 2X less than the 5DX AXI system and the radiation dosage of the 5DX is well below industry requirements for safety.

FAQ 2007-04-22

How is the high throughput achieved
The x6000 Automated X-ray Inspection System provides high throughput because of the changed system design along with an architecture that allows for fast image acquisition and analysis.

FAQ 2007-04-22

IO Libraries Suite: What are the terms of the Licensing Grant?
For every individual Keysight instrument, Keysight hardware I/O product (including Keysight GPIB cards and Keysight I/O converters)…

FAQ 2007-01-08

Why does the DC Gain Error formula in the DC Gain Accuracy procedure have factors of 0.60 and 0.75 in the DSO80000 Series Infiniiums but not the ot...
These factors are used in the DSO80000 Series Infiniiums because the DC gain is measured with input voltages that are less than full scale, but the spec is relative to a full scale input.

FAQ 2006-10-20

The N5120A Technical Overview says “Timing Characterization +/-1/32 chip (4 ns)”; however, a chip is 260 ns so +/-1/32 chip would be 16 ns. Why...
This is an error and should have stated “Timing Characterization 1/64 chip (4 ns)”.
