Measurement details

All of the RF transmitter measurements as defined by the 3GPP standard, as well as a wide range of additional measurements

and analysis tools, are available with a press of a button (Table 3). These measurements are fully remote controllable via the

IEC/IEEE bus or LAN, using SCPI commands.
