12 SYSTem Subsystem
526 N1911A/1912A P-Series Power Meters Programming Guide
SYSTem:PRESet <character_data>
This command presets the power meter to values appropriate for
measuring the communications format specified by <character_data>. The
power meter is preset to default values if no value or the value DEFault is
supplied.
For further information on preset configurations, refer to
Table 12- 26 through to Table 12- 83.
Command results differ according to the sensor(s) connected to the power
meter:
• If connected to a dual channel power meter, a P- Series or E9320
sensor are connected to one channel, and another model sensor is
connected to the other channel, the channel connected to the P- Series
or E9320 sensor is set up according to the <character_data> value and
the other channel is set to DEFault values.
• If two P- Series or E9320 sensors are connected to a dual channel
power meter, both channels are set to the same values except for
bandwidth which is set to an appropriate value for each sensor.
Primary and Secondary Channels
Dual channel meter channels are defined as either primary or secondary.
The primary channel is always the trigger master and primary channel
measurements occupy a greater share of the display space than secondary
channel measurements.
• If a dual channel meter has a P- Series sensor connected, the P- Series
or E9320 sensor channel is the primary channel. In such cases the
primary channel could be either Channel A or Channel B. The other
model’s channel is the secondary channel.
• If a dual channel meter has two, P- Series or E9320 sensors, connected
to it, the primary channel is always Channel A and the secondary
channel is Channel B.
DEFault settings apply to both *RST and to
SYSTem:PREset DEFault unless stated otherwise.
