1GP71_0E 76 Rohde & Schwarz
QS
Step backward to previuous register and recall setup.
RP
Reset reverse power protection.
Table 66: Other commands
Instrument initialisation
The (factory) default setting of the HP8340 is applied when
o applying the DCL, SDC to the GPIB interface.
o transmitting the first command after activating this emulation mode.
During initialisation, the HP8340 applies and activates the backup register set
0.
The SM* however applies and activates the (factory) default setting of the
HP8340.
This different behaviour has to the be taken in consideration:
It is strongly recommended to explicitly setup all necessary parameters
by applying the corresponding command.
The following table shows the (factory) default setting, applied by the SM*’s
emulation software.
Subsystem Default setting
frequency mode start / stop frequency sweep mode
start frequency lowest possible value of SMF100
(depends on installed options)
stop frequency highest possible value of SMF100
(depends on installed options)
center frequency = 0.5 * (start frequency + stop frequency)
delta frequency = stop frequency – start frequency
cw frequency = center frequency
sweep mode continuous sweep mode
trigger mode freerun trigger mode
sweep time 44ms
marker states off
marker frequency = center frequency
amplitude modulation off
pulse modulation off
frequency modulation off
