Example 3 : dBm Measurement

Purpose: To achieve dBm measurement.
dBm is a commonly measure units which widely used in electrical, radio, mechanics,
shock and vibration, mechanical power and acoustics, and other fields, and dBm
caluation is usually used for RF signal measurement.
The programming steps:
0 *RST
1 *IDN?
2 :function:resistance
3 :measure□AUTO
4 :measure:resistance?
/*measure the reference resistance for dBm calculation*/
5 :function:voltage:AC
6 :measure□AUTO
7 :calculate:function DBM
8 :calculate:DBM:reference □ <value>
calculation*/
9 :calculate:DBM?
Remark:
1. Before sending the fourth command, please connect equipment according to
resistance measure type.
2. The parameter of eighth command is the above measurement resistance.
