FAQ 2011-07-24

把 Keysight Intuilink 4395A 连接到 4395A, 4396B 分析仪上发生异常
错误是由于分析仪的内存RAM磁盘被格式化为LIF引起的。把磁盘重新格式化为DOS驱动器,应用程序将正确运行。

FAQ 2011-06-28

我使用 Keysight 4395A / 4396B 组合分析仪的频谱分析仪模式(包括噪声格式)时,把单位设置为 V(伏特),但游标显示为‘nV / Hz’。在此模式下,显示的单位是否有误?
由于 4395A / 4396B 的显示限制,屏幕注释无法正确显示设定的单位‘nV / √Hz’。

FAQ 2011-06-27

当通过 Keysight IntuiLink 4395A / 4396B / 49294A 使用 Keysight 4294A 阻抗分析仪时,Excel 软件报告错误“Failed to Capture State from Instrument(无法从仪器捕获状态)”。您有什么建议?
当 4294A 固化软件的版本低于 Rev 1.11 或更高版本所要求的版本时,便会出现下面的错误提示。

FAQ 2011-06-12

E4980A/ 4263B/ 4284A/ E4981A 无法对特殊的测试夹具进行开路/短路补偿时,该如何检查测试夹具中的异常情况?

FAQ 2011-06-06

当直流偏置电流超过一定限度时,为什么 42841A 会关闭,而且在 E4980A/ 4284A 上还会显示“E25: DC bias I source overload”或“E26: DC bias I sink overload”错误消息?
42841A 输出的直流偏置电流不能超出由被测件直流电阻和直流输出电压最大极限值决定的电流限度。

FAQ 2011-04-21

当 4263B 上显示“OVLD”信息时,我应做什么?
当被测阻抗超出量程时,LCD 上就会显示“OVLD”提示。

FAQ 2011-04-21

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

当显示“警告,ALC 不能调整”时,E4980A / 4284A 能否测量被测件?
能,虽然无法将测试信号电平控制在 ALC 设置值上,但 E4980A/ 4284A 仍能测量被测件。

FAQ 2010-01-26

E4980A/4284A LCR 表显示“ALC 不能调整”的错误消息时,应执行哪些纠正措施?

FAQ 2009-08-13

What should I perform when the 4287A displays an “OVLD” message?
First, check if the DUT has properly contacted the test fixture’s electrodes. If no contact error is found, check for a possible failure of the 4287A.

FAQ 2009-03-11

How can I clear an error message shown on the display of the 4294A/4395A/4396B by using GPIB command?
Send the "KEY 18" command to the instrument.

FAQ 2009-01-08

Why is "OVERLOAD" message sometimes displayed in Network Analyzer mode of the 4395A? How can I avoid this error message?
The OVERLOAD message on the 4395A Network Analyzer mode is often displayed when Sweep Start frequency is lower than 5 kHz and a wide IFBW is selected.

FAQ 2008-11-17

当 4338B 上显示“OVLD”信息时,我应做什么?
当被测阻抗超出量程时,LCD 上就会显示“OVLD”提示。

FAQ 2008-11-12

Why does the E4980A display OVERLOAD when DC bias current setting is above 20 mA?
If the DCI range has been set to 20 mA (default setting), change it to AUTO or 100 mA range.

FAQ 2008-11-12

当 4339B 上显示“OVLD”信息时,我应做什么?
当被测阻抗超出量程时,LCD 上就会显示“OVLD”提示。

FAQ 2008-10-29

How can I get the error code from the 4263B if the controller doesn't indicate a specific error code?
Send ":SYSTem:ERRor?" query and read the response to this query in character format.

FAQ 2008-09-24

When does the 4339B display "OVLD"?

FAQ 2008-09-11

What should I do when the "RF overload" message is displayed on the E4991A?

FAQ 2008-09-11

What should I perform when the "ADC OVERLOAD" message is displayed on the 4294A LCD during a measurement?
The ADC OVERLOAD error message is displayed when the detected signal level exceeds a normal range due to, for example, abrupt changes in DUT contact condition.

FAQ 2008-09-11

4294A sample programs don't work and error 173 "Active/System controller required." is displayed. How can I fix this symptom?
Since the SYSTEM ID of the 4294A has changed, depending on the firmware version, the program lines which refer to the SYSTEM ID needs to be modified.

FAQ 2008-09-11

How can I clear the data buffer memory of the E4980A when an error message "E90: Data buffer overflow" appears?
Use :MEM:CLE DBUF command or press "SAVE & STOP" softkey.
