When OUTPut1:IMPedance is set to either 50Ω or 75Ω, either no output attenuation
or 20 dB may be selected. OUTPut1:ATTenuation must be set to
0dB when OUTPut1:IMPedance is set to 0Ω.

:OVERload?
OUTPut1:OVERload? determines if an overload condition exists by reading bit 11
of the amplifier’s status register (Appendix C).
Comments
• A one (1) returned in response to the query indicates an overload condition exists.
A zero (0) indicates there is not an overload condition.
• Coupling group: none
• *RST Condition: none
