1 RH is the abbreviation for relative humidity.
2 Average hourly drift, at constant temperature. It is recommended to wait for 3 minutes and perform zeroing before taking
the measurement. For N8487A with serial number MY48700101 to MY54089999 and N8488A with serial number
MY50230001 to MY540899999, it is recommended to wait for 30 minutes and perform zeroing before taking
the measurement.
3 The number of averages at 16 for normal mode and 32 for x2 mode, at a constant temperature, measured over one minute
interval and two standard deviations.
4 The zero set, zero drift, and measurement noise specifications are tested at 50 MHz.
5 N/A is the abbreviation for “not applicable”.
