HP 75000 SERIES C User Manual

If the reference source is INT this condition is
always set.
The condition is checked every 0.2 seconds.
Main
VCO unlock
This condition is set when the main VCO loop
is out of lock, indicating a hardware fault.
The condition
is checked every 0.2 seconds.
Volt age
This condition is set when the instrument is
unable to do
a successful amplitude calibration,
indicating a hardware fault.
It is updated every time a amplitude
calibration is done
(explicit by command CAL? or implicit by a
change of the output function).
Sample Program
This example RMBASIC program demonstrates the use of the
E1440A Status registers. The program does the following
:
Forms two BASIC SUB's -
Statusinit (Address) and
Err-check(Address)
These SUB's might be helpful during test program development.
Statusinit should be called at the beginning, For quick debugging,
Err-check might be called after each programming cycle of the
E1440A.
Note
A common problem must be overcome here: we have to ensure that
)41
the E1440A has seen $1 commands before looking for errors. The
"OPC? command is ideal for this.
For easy ON/OFF switching we define a common named 'debug'
to
control the behavior of the SUB's
Program
COM /Debug/ INTEGER Err-check
REAL El440
! for the instrument VXIbus address.
! Notice that an INTEGER is too small to hold
! a VXIbus address with secondary addressing.
!
E1440=70911 ! assumed slot 0 commander is connected to
! VXIbus interface with select code 7,
! primary VXIbus address of slot 0 commander is 9
! and logical address of E1440A is 88 (secondary
! VXIbus address is logical add. shifted left 3 bits)
!
Err,check=l ! we want to do error checking, set to 0 if You don't
