The calibration of the plug-ins can be made via hard and softkeys, but the mainframe calibration is protected by a dip switch. Why?
The mainframe calibration requires external equipment for calibration. The procedures for this timebase calibration are in the 83480A Service Manual. It is important to meet the trigger requirements in the procedures to be able to perform a timeba...

Can the temperature change be read out via GPIB?
Yes, both the main frame and plug-in module delta temperature can be read out via GPIB...

FAQ 2004-04-08

The manual says an o/e converter cal is recommended if a wavelength other than the factory default is used. What is the minimum deviation of wavele...
We recommend an o/e cal if the wavelength is > 20 nm away from the cal wavelength.

FAQ 2004-04-08

Why does the 54750A and/or 83480A screen say 'Plug-in X is uncalibrated'? X can be 1 or 3 depending on the slot the module is in.
The above screen message is displayed if the vertical channel calibration is required. This can be caused by several conditions...

FAQ 2004-04-08

What does a ROM Check Sum failure during instrument self test mean?
If the mainframe contains a Beta version of firmware, the ROM self test will always produce a ROM Check Sum error. The ROM Check Sum is set when a new release version is produced. Normal production release versions of firmware have the format A.0x...

FAQ 2004-04-08

Why does the Extinction ratio dark cal take longer sometimes?
The dark calibration routine checks the plug in calibration status at the start of dark cal. If the plug in calibration status is 'uncalibrated', it first performs the plug in calibration and then performs the dark calibration...

FAQ 2004-04-08

The 83480A displays 'cal status' 'current frame delta temp' a difference of + 8°. Do I need to make a calibration?
Yes, the manual recommends making a calibration if the temperature changes more than +/- 5°c. A mainframe calibration of the timebase is recommended. It is possible that the mainframe may still meet the time interval accuracy specifications even t...

FAQ 2004-04-08

Is it possible to do a cal via GPIB?
Yes, the plug-in cal can be performed remotely.

FAQ 2004-04-01

Infiniium Oscilloscopes: Can I use the scope as a PC (personal computer)?
No. At the present time, the Keysight Infiniium Oscilloscope is a closed system and other applications may not be installed on the scope.

FAQ 2004-03-31

Infiniium Oscilloscopes: I have a 500 mV p-p signal. Can I look at the details at 1 mV/Div?
You should not look at the details of this signal by just changing the vertical scale (V/Div) because of hardware limitations found in most scopes. Instead, use software magnification to get more accurate, detailed information.
