requirement for logarithmic sweep. The
sweep type is automatically changed to
linear sweep when this error occurs.
For example, this error occurs when, with
the start and stop frequency are set 1 MHz
and 2 MHz respectively, the sweep type is
changed to logarithmic sweep.
Set the stop frequency to more than four
times as many as the start frequency. And
then select logarithmic sweep.
Description
The number of parameters is less than that
required for the command, or the
parameter has not been entered. For
example, the command SENS{1-
6}:SWE:POIN requires one more
parameter.
Therefore, when a message
"SENS1:SWE:POIN" is sent to a correct
program message "SENS1:SWE:POIN 201"
this instrument receives the former
message as an invalid one because all
parameters have not been entered. Enter
command parameters correctly.
Description
The GPIB system controller is not set
properly.
This error occurs when USB/GPIB interface
is not connected or the interface setting is
improper, during the measurement for
power calibration data or for that in scalar-
mixer calibration.
It also occurs when USB/GPIB interface is
not connected or the interface setting is
improper, though the control of the
external signal source is enabled.
