Why does pressing preset perform a user preset on my Agilent Technologies n5181a?
This behavior results from the use of a backward-compatible SCPI command. To return the signal generator to normal use, send the command `:SYST:PRESet:TYPE NORM.`
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.
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.
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.
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**.
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.
What to do if I receive ERROR 224, Text file busy on my Agilent Technologies Inverter?
The 'ERROR 224, Text file busy' on your Agilent Technologies Inverter happens when you try to download a waveform with the same name as one currently playing on the signal generator. You can either change the name of the waveform you're downloading or turn off the ARB to fix this.
Why does the sweep appear stalled on my Agilent Technologies n5181a?
If the sweep appears stalled on your Agilent Technologies Portable Generator, consider the following: * Turn on the sweep using one of these key sequences: **Sweep > Sweep > Freq**, **Sweep > Sweep > Amptd**, or **Sweep > Sweep > Waveform** (vector instruments only). * If the sweep is in single mode, press the **Single Sweep** softkey. * If the sweep trigger is not set to Free Run, set it to Free Run to determine if a missing sweep trigger is blocking the sweep. * If the point trigger is not set to Free Run, set it to Free Run to determine if a missing point trigger is blocking the sweep. * Set the dwell time to one second to determine if the dwell time was set to a value that was too slow or too fast to see. * Make sure that you set at least two points in the step sweep or li...
What to do if Agilent Technologies Portable Generator does not respond?
If the signal generator does not respond to a preset, the instrument may be in remote mode, which locks the keypad. To exit remote mode and unlock the preset keys, press **Local Cancel/(Esc)**.
Why is the instrument state saved, but the register is empty or contains the wrong state on my Agilent Technologies n5181a Portable Generator?
If the register number you intended to use is empty or contains the wrong instrument state, recall register 99. If you selected a register number greater than 99, the signal generator automatically saves.
