6-127. Leveled Sine Wave Flatness Verification

Leveled Sine Wave flatness verification is divided into two frequency bands: 50 kHz to
10 MHz (low frequency) and > 10 MHz to 300 MHz (high frequency). The equipment
setups are different for each band. Leveled Sine Wave flatness is measured relative to 50
kHz. This is determined directly in the low frequency band. The high frequency band
requires a "transfer" measurement be made at 10 MHz to calculate a flatness relative to
50 kHz.

6-128. Equipment Setup for Low Frequency Flatness

All low frequency flatness procedures use the following equipment:
•
•
•
Connect the Calibrator Mainframe SCOPE connector to the 5790A WIDEBAND input
with the BNC(f) to Type N(m) adapter as shown in Figure 6-25. Set the 5790A to
AUTORANGE, digital filter mode to FAST, restart fine, and Hi Res on.

6-129. Equipment Setup for High Frequency Flatness

All high frequency flatness procedures use the following equipment:
•
•
•
•
When high frequencies at voltages below 63 mV p-p are verified, use the
8481D Power Sensor. Otherwise, use the 8482A Power Sensor.
