The power available from the tester depends on the connector in use. When using the RF IN/RF OUT connector, the
power range, assuming no external attenuation or gain, is –133.0 dBm to –70.0 dBm to –19.0 dBm. When using the RF
OUT 2 connector under the same conditions, the power range is –113.0 dBm to –70.0 dBm to +1.0 dBm.
123
If external gain or attenuation is used (through the command tree ”SOURce:CORRection: LOSS:...”), the internal power of
the tester is adjusted to maintain the commanded power after the attenuation or gain. However the limits will change. For
example, if there is 10 dB of external loss (attenuation), the output range for the RF IN/RF OUT connector will be –143.0
dBm to –70.0 dBm to –29.0 dBm. Note that the default power remains the same provided that the tester can output the
required power, given the external attenuation or gain.
124
If the tester is in the IDLE state, the power range accepted as defined by the MAXimum and MINimum arguments, or as
returned in response to the MAXimum or MINimim queries, is the widest range which can ever be obtained using either
RF output and the full range of attenuation and gain values accepted by the ”SOURce:CORRection:LOSS...” command
tree (–183.0 dBm to –70.0 dBm to 41.0 dBm). If the output power is set outside the limits that the tester can produce, when
the instrument leaves the IDLE state the power will be set to the closest end of the range for the output connector and
external attenuation (or gain) in use.
125
The “Gain error” is the same as that returned by the query ”CONFIGure”MPILots:GAINerror?”. See its description and
footnote for further information.
126
If the associated gain setting “CONFIGure:MPILots:p4gain” (or “p5gain”) has been set to HIGH, the limits are –20 dB to
–18 dB to –5.0 dB.
