CW Power Measurement from +20 dBm to –35 dBm
The following programming sequence examples measure continuous wave (CW)
power from +20 dBm to –35 dBm with Free Run and Single Trigger modes.
Free run
-> SYST:PRES DEF // Presets the U8480 Series.
-> FREQ 1000MHz // Sets the frequency to 1000 MHz.
-> CAL:ZERO:AUTO ONCE // Performs zeroing.
-> *OPC? // Waits for the operation to complete.
<- 1 // Returns a 1 when zeroing has completed.
-> INIT:CONT ON // Sets the U8480 Series to the Free Run
mode.
NOTE
It is strongly advisable to perform zeroing on the U8480 Series for power
measurement levels below –30 dBm for accurate measurements. During the
zeroing process, the RF input signal must be switched off or the
device-under-test disconnected from the U8480 Series.
-> FETC? // Queries the measurement results.
NOTE
It is advisable to use FETC? to query the measurement results. MEAS? can also
be used but it will trade off the measurement speed.
-> MEAS? // Reads the measurement results.
