B.100 SYSTem:MODE COMMAND
SYST:MODE
Syntax:
Short Form: SYST:MODE <TRANS | FIX | EXT>
Long Form: SYSTem:MODE <TRANsient | FIXed | EXTernal>
Description: Initiates a transient. Sending SYST:MODE TRANS initiates a transient pulse. The operating MODE
(PAR. B.40) determines the type of transient (voltage, current, conductance or resistance) and the
transient parameters are determined by the corresponding transient command: for voltage see
VOLT:TRAN, (PAR. B.62), for current see CURR:TRAN (PAR. B.38), for conductance see
COND:TRAN (PAR. B.30) and for resistance see RES:TRAN (PAR. B.50).
Sending SYST:MODE FIX terminates SYST:MODE TRANS and disables analog programming (sets
SYST:EXT (see PAR. B.96) to OFF.
Sending SYST:MODE EXT terminates SYST:MODE TRANS and enables analog programming (sets
SYST:EXT (see PAR. B.96) to ON.

SYST:MODE?
Syntax:
Short Form: SYST:MODE?
Long Form: SYSTem:MODE?
Returns <TRAN | FIX | EXT>
Description: Indicates SYSTem:MODE status. Returns TRANS if transient is enabled, returns FIX if both transient
and analog programming are disabled, and returns EXT if analog programming is enabled.
A = Transient <value>
B = SYST:RAMP:POS <time> or RAMP POS time from front panel
C = SYST:RAMP:NEG <time> or RAMP NEG time from front panel
D = Transient <time> (no ramp)
E = Transient <time> (with ramp)
F = Transient <period> (no ramp)
G = Transient <period> (with ramp)
Positive
Ramp
Negative
Ramp
Transient pulse
(Count = 3)
NOTE: TRANSIENT WILL NOT EXECUTE IF:
1. B > D
2. E + C > G
