Why is the list sweep information missing from a recalled register on my Agilent Technologies n5181a?
List sweep information is not stored as part of the instrument state in an instrument state register. Only the current list sweep is available to the signal generator. You can store list sweep data in the instrument catalog.
What causes signal loss while working with a mixer and Agilent Technologies n5181a Portable Generator?
To fix signal loss at the signal generator’s RF output during low-amplitude coupled operation with a mixer, add attenuation and increase the RF output amplitude.
What causes signal loss while working with a spectrum analyzer and Agilent Technologies n5181a?
The effects of reverse power can cause problems with the RF output when you use the Agilent Technologies Portable Generator with a spectrum analyzer that does not have preselection. Use an unleveled operating mode to resolve this.
Why is there distortion in the output signal of my Agilent Technologies Portable Generator?
If you edit and resave a segment in a waveform sequence, the sequence does not automatically update the RMS value stored in its header. To resolve distortion, display the sequence header information and recalculate the RMS value.
How to turn off sweep on Agilent Technologies n5181a?
To turn off the sweep function on your Agilent Technologies Portable Generator, press **Sweep > Sweep > Off**.
What to do if there is no modulation at the RF output of my Agilent Technologies n5181a?
If there is no modulation at the RF output, try the following: * Check both the Mod On/Off LED and the Off On softkey, and ensure that both are on. * If you're using a vector signal generator with digital modulation, make sure that the internal I/Q modulator is on (the I/Q annunciator should be displayed). * If you're using an external modulation source, verify that the external source is on and operating within the signal generator’s specified limits.
What to do if Agilent Technologies n5181a Portable Generator power supply shuts down?
If the power supply of your Agilent Technologies Portable Generator isn't working, it likely requires repair or replacement. If you cannot service it yourself, send the signal generator to an Agilent service center.
Why is the RF output power too low on my Agilent Technologies n5181a?
There are several reasons why the RF output power might be too low on your Agilent Technologies Portable Generator: * If the AMPLITUDE area of the display shows the OFFS indicator, eliminate the offset by pressing **Amptd > More (1 of 2) > Amptd Offset > 0 > dB**. * If the AMPLITUDE area of the display shows the REF indicator, turn off the reference mode by pressing **Amptd > More > Amptd Ref Off On** until Off highlights. Then, reset the output power to the desired level. * If pulse modulation is on, turn off the ALC, and check that pulse width is within specifications.
