Recall_Work?
Recall_Work? provides a way of returning all the set-ups in the amplifier. The
information is returned in the format used to set up the amplifier provided Header
was not set to OFf. This makes it possible for the data to be stored in a file and
saved until a later time. By sending the complete file to the amplifier at a later
time, the amplifier is set up with the same settings as when the information was
received from the amplifier.
Note: Interface parameters are not returned since they can only be set manually.
The information returned by the amplifier after receiving the Recall_Work? query
includes the following:
● Channel_1 (channel-dependent) parameter settings (for the 2525 always
Channel_1)
● Main_Set_Up (channel-independent) parameter settings
Example (long):
:Channel_1:Measurement_Mode Acceleration;Transducer_Sensitivity 1E-12;
Input_Type Charge_Single_Ended;Input_Gain -20;Fine_Gain 0;
Output_Gain 0;Upper_Frequency_Limit 10000;Lower_Frequency_Limit 1;
Additional_Filter None;Rms_Averaging_Time Exponential,1;
Peak_Hold_Time 5;Auto_Range OFf;Alarm_On_Off OFf;Alarm_Detector
*Note that some parameters may have more than one value, in which case the
parameters are separated by a comma.
