HP 1630A Operating And Programming Manual page 110

Model 1630A/D/G
DW
- DisplayWrite . Writes ASCII string of 80 or less characters to analyzer display, beginning at position
specified by row and column .
SYNTAX : DW[I] <ROW><COL> (STRING) ;
where I is optional parameter specifying that string be displayed in inverse video .
Legal delimiters for STRING are ",", and ( ) .
Using HP-IB or HP-IL Interface
ID
- Send Identification code . Causes analyzer to send identification code indicating instrument
configuration followed by CR LF .
SYNTAX : ID ;
where returned value is a string containing the instrument model number ("HP1630A", "HP1630D"
or "1630G") .
HP1630A - (35-channel state, 8 timing)
HP1630D - (43-channel state, 16 timing)
HP1630G - (57-channel state, 8 timing)
KE
- Send buffered key . Causes analyzer to send key mnemonic or alphanumeric character followed by
CR LF for any key (refer to table 9-1) that has been pressed while in remote mode . Buffer saves up to
the last 15 key presses . If no keys have been pressed, the analyzer returns double questions marks
SYNTAX : KE ;
MB
- Set service request mask byte . Enables SRO, PP response, and bits in the serial poll and SB1
registers specified in argument . Mask byte is set to 0 at power-on, disabling any service requests .
SYNTAX : MB <mask-value> ;
where mask-value is an ASCII integer (i .e ., 0 to 255) in decimal format. A service request (SRO)
will be generated if the mask bit for a condition is set to one and that condition occurs . The mask bit
positions are :
Bit 4 (16) = Not Busy
Bit 5 (32) = Error in Last Command
PU
- Power-up . Defaults all instrument menus . Buffered keys, SRO, PP and status bytes are unmodified .
SYNTAX : PU ;
RST
- Reset . Reset analyzer to power-up condition as if power was cycled . A one second delay is
recommended after RST prior to sending any other remote commands .
SB
- Status Byte . Returns analyzer status byte to controller on next read . One of four status bytes maybe
requested . Status bytes are returned as a single byte without termination . The character decimal
value returned represents the status .
SYNTAX : SB N ;
where N is an integer value from 1 to 4 . If argument N is omitted, the default condition is status byte
1 . Requesting status byte 1 or executing a serial poll resets the SRO and PP response and clears the
bits in the serial poll or SB1 register .
Bit 0 ( 1) = Print Complete
Bit 1 ( 2) = Measurement Complete
Bit 2 ( 4) = Slow Clock
Bit 3 ( 8) = Key Pressed (Front Panel Request)
