System Commands
TIME(?) [ SEConds | MINutes | HOUrs | j ] { , i }
The TIME j, i command sets the clock value for seconds (j=0), minutes (j=1) or hours
(j=2) to i.
Example
TIME MIN, 30 Set the system clock minutes to 30
TIME 1, 30
TIME? MIN
Returns the system clock minutes
DATE(?) [ DAY | MONth | YEAr | j ] { , i }
The DATE j, i command sets the clock value for day (j=0), month (j=1) or year (j=2) to i.
The value of i is limited to 0
–
99.
Example
DATE YEAR, 21 Set system clock year to (20)21
DATE 2, 21
DATE? YEAR
Returns the system clock year (last 2 digits)
TBMODE(?) { AUTO | INternal | i }
The
TBMODE i
command sets the external 10 MHz timebase mode to auto (i=0) or
internal (i=1).
Example
TBMODE AUTO Set the timebase mode to auto
TBMODE 0
TBMODE?
Returns the timebase mode i
TBSTAT?
The
TBSTAT?
query returns the current 10 MHz timebase source, either external (0) or
internal (1).
Example
TBSTAT? Returns the current 10 MHz timebase
BLAZEX(?) { BLazex | BIsync | UNIsync | i }
The BLAZEX i command sets the rear panel BlazeX output to blazex (i=0), bipolar sync
(i=1) or unipolar (positive) sync (1=2).
Example
BLAZEX UNI Set the BlazeX output to unipolar sync
BLAZEX 2
BLAZEX?
Returns the BlazeX output selection i
