To Receive Measurement Trigger
To use an external trigger just for starting measurement, instead of the XE
command, perform the next step. This is not effective for the high speed spot
measurement.
1. Connect a BNC cable between the Ext Trig In connector and a trigger output
connector of an external device.
2. Create a control program. Then the TM3 command and HP BASIC ENTER
statement should be entered as shown in the following example:
:
OUTPUT @E5270;”MM1” ! Sets spot measurement mode
: ! Sets measurement condition
:
OUTPUT @E5270;”TM3” ! Uses external trigger
ENTER @E5270 USING ”#,3X,12D,2X”;M_data
:
3. Execute the control program.
The E5260/E5270 sets the measurement conditions, and waits for an external
trigger (negative trigger) sent to the Ext Trig In connector.
When the trigger is received, the E5260/E5270 starts measurement. When
measurement is completed, the E5260/E5270 sends a negative edge trigger to
the Ext Trig Out connector, and puts the measurement data in the data output
buffer.
NOTE The HP BASIC ENTER statement pauses program execution until measurement
data is put in the data buffer, reads the data from the buffer, and then continues
program execution.
