ESA Functional Tests
Tracking Generator Level Flatness: Models E4401B and E4411B, Options 1DN and 1DQ Test Limits
Test Description
A calibrated power sensor is connected to the tracking generator output to measure the
power level at 50 MHz. The power meter is set for REL mode so that future power level
readings are in dB relative to the power level at 50 MHz. The tracking generator is then
stepped to several frequencies throughout its range. The output power difference relative
to the power level at 50 MHz is measured at each frequency and recorded. Analyzers with
75 Ω tracking generators are only tested from 1 MHz to 1500MHz.
Maximum Maximum
Flatness ≤ 10 MHz, 50 Ω–2.5 dB 2.5 dB
Flatness > 10 MHz, 50 Ω–2.0 dB 2.0 dB
Flatness > 10 MHz, 75 Ω–3.0 dB 3.0 dB
Flatness > 10 MHz, 75 Ω–2.5 dB 2.5 dB
