Setting Up A Typical
Sweep, Example
Program 3
In swept operation, the swept signal generator is programmed for the
proper sweep frequency range, sweep time, power level, and marker
frequencies for a test measurement. This program sets up the swept
signal generator for a general purpose situation. The instrument is
the same as in program 1. Clear and reset the controller and type in
the following program:
10 Source=719
20 ABORT 7
LOCAL 7
30
40 CLEAR Source
50 REMOTE Source
60 OUTPUT Source;"*RST"
70 OUTPUT Source;"FREQuency:MODE SWEep"
80 OUTPUT Source;"FREQuency:STARt 4 GHZ"
90
OUTPUT Source;"FREQuency:STOP 7 GHz"
100 OUTPUT Source;"POWer:LEVel -5 DBM"
110 OUTPUT Source;"SWEep:TIME
120 OUTPUT Source;":MARKerl:STATe 0N;FREQuency 4.5GHZ"
130 OUTPUT Source;"MARKer2:STATe 0N;FREQuency 6111E6"
OUTPUT Source;"*OPC?"
140
150 ENTER Source;X
160 OUTPUT Source;"POWer:STATe ON"
170 OUTPUT Source;"INITIate:CONTinuous ON"
180
190 PRINT "Source setup complete."
200 PRINT "Verify that the source is sweeping from"
210 PRINT "4 GHz to 7 GHz at a power of -5 dBm,"
PRINT "with a sweeptime of 0.5 seconds."
220
END
230
Run the program.
Program Comments
10: Assign the source's HP-IB address to a variable.
20 to 50: Abort any HP-IB activity and initialize the HP-IB
interface.
60: Set the source toitsinitial state for programming. The *RST
state is not the same as the PRESET state. For complete details
of the instrument state at *RST, see "SCPI Command Summary,"
in Chapter 2.
70: Select the frequency mode to be SWEEP instead of the default
sweep mode of "CW" that was selected with *RST.
80: Set the source start frequency to 4 GHz.
90: Set the source stop frequency to 7 GHz. Note the optional
usage of the short-form mnemonic, "FREQ".
100: Set the source's power level to -5 dBm.
