I am using a E4417A power meter in peak configuration. I have external triggering enabled. I am finding that when I have an offset out in at 51dB I am recieveing a sensor overload when the sensor see a raw signal >+5dBm. The sensor is rated to +20dBm. If I run the meter with the offset set to zero then no overload occurs.
This has duplicated with two separate meters and with two different power sensors. The RF signal also has been both pulsed and CW with the same results.
