Warning Message
A warning message is displayed in the instrument message/Warning area in the lower-left
part of the display against a gray background. Touching Entry Off key at the front panel
executing the :DISPlay:MESSage:CLEar command on page 237 clears the message.
Moreover, about a specific warning message, when a sweep is started again, a warning
message may disappear.
This message simply appears on the display, since it is not known to remote environments
such as a GPIB. This message is not displayed when another error message (against a red
background) has already been displayed in the instrument message/Warning area.
The warning messages for this instrument are as follows:
571 DC control out of limit
This message occurs when the specified DC control voltage or the sweep start/stop DC
control voltage for the frequency & power measurement is out of the maximum/minimum
allowed voltage of DC control.
580 DC control output on required in AFC
The automatic frequency control function was set on, however, the power or control
voltage is not being applied to the DUT. Verify that the control voltage output is set to ON.
570 DC power out of limit
This message occurs when the specified DC power voltage or the sweep start/stop DC
power voltage for the frequency & power measurement is out of the maximum/minimum
allowance voltage of DC control.
560 Incompatible recall file
This message occurs when an incompatible file is read.
550 Marker tracking failed
This message occurs when marker tracking fails.
503 Set RF ATT 0dB
This message occurs when the input attenuator is set improperly. Set the input attenuator to
0 dB.
504 Set RF ATT 5dB
This message occurs when the input attenuator is set improperly. Set the input attenuator to
5 dB.
505 Set RF ATT 10dB
This message occurs when the input attenuator is set improperly. Set the input attenuator to
10 dB.
506 Set RF ATT 15dB
This message occurs when the input attenuator is set improperly. Set the input attenuator to
15 dB.
507 Set RF ATT 20dB
This message occurs when the input attenuator is set improperly. Set the input attenuator to
