.
:ATTenuation:AUTO:HOLD:TIME? MIN | MAX
Query about the selected hold time.
Parameters:
none
query about the current hold time
MINimum|MAXimum
query about the minimum/maximum hold time
Result:
Hold time in seconds.
Example:
INPut:ATTenuation:AUTO:HOLD:TIME? -> 3
.

:MODE LOWDistort| LOWNoise|NORMal
Selection of operating modes for different receiving conditions.
In module "Preselection" there is a selectable amplifier behind the range filters.
When "
Low Distortion
" is selected, the amplifier is cut off. This achieves the best linearity but the noise
figure will be correspondingly higher. This setting is especially recommended for areas with a lot of
strong signals.
When "
Normal
" and "
Low Noise
" is selected, the amplifier is cut in. This achieves a good noise figure
and at the same time good high-level signal characteristics because the receiving bandwidth is limited
in front of the amplifier. This setting is recommended for normal receiving conditions.
At this setting with ATT OFF, excessively strong signals (approx. >97 dBµV) at the antenna entry may
cause an overload of the A/D converter.
Notes:
As opposed to the EM550, the EM510 modes "
Normal
“ and "
Low Noise
“ are identical in meaning.
However, both modes are permitted for reasons of compatibility.
Parameters:
LOWDistort
low-distortion reception
NORMal | LOWNoise
normal reception, low-noise reception
*RST state:
NORMal
Example:
INPut:ATTenuation:MODE LOWDistort
.
.
:MODE?
Query about the selection of operating modes for different receiving conditions.
Parameters:
none
Result:
LOWN
reception with low noise
