RF Generator mode
Some RF Explorer models can generate a CW RF tone or a configurable sweep for testing RF receivers and
simulating interference very easily.
 Frequency: Transmit frequency in MHZ in single tone mode, or start frequency in MHZ in sweep
mode.
 Power: Transmit power in dBm, increasingly changed by 3dB steps each time [Enter] key is pressed.
Accuracy is typically +-3dB and can be significantly influenced by the matching load. Pure 50 ohm
loads will give better results than loads with some high VSWR values due to impedance unmatched,
for instance an antenna not tuned for the transmit frequency.
 Transmitter: Switch to ON to start transmitter, to OFF will stop the transmitter. It is important to
switch the transmitter to ON only when a load is connected.
 Sweep steps:
o When defined to 1, the RF Generator will work in single tone mode. In this mode it will
permanently transmit a CW on the frequency specified.
o When defined to any value from 2 to 255, the RF Generator will work in sweep mode. In this
mode it will transmit a tone starting on the frequency specified, and then will hop to a
frequency value that is Step freq MHZ higher, lasting Step time milliseconds, till it reach the
number of steps. After the last programmed frequency is transmitted it will go back to the
first frequency, repeating the cycle till the transmitter is set to OFF by the user.
 Step time: Defines the milliseconds to transmit each tone before the next hop. Valid range is 5-
255ms. Used in sweep mode only.
 Step freq: Defines the incremental frequency of each hop in the sweep. Valid ranges goes from
0.010 to 2.55 MHz. Used in sweep mode only.
