Section 6 Performance Tests
Reference level accuracy
Here the absolute amplitude level at only 50 MHz is tested. Confirm the level accuracy
after inputting an SG output (calibrated by a standard power meter) to the MS8608A/
MS8609A.
(1) Specification
• Reference level accuracy: At 50 MHz frequency and 1 MHz span after automatic
calibration
(Resolution bandwidth, video bandwidth, RF ATT and
sweep time set to AUTO)
■
MS8608A High power input
≤±
0.5 dB (–29.9 to +20 dBm)
≤±
0.75 dB (–49.9 to –30 dBm, +20.1 to +40 dBm)
≤±
1.5 dB (–60 to –50 dBm)
■
MS8608A Low power or MS8609A input
≤ ±
0.5 dB (0 to –49.9 dBm)
≤ ±
0.75 dB (–69.9 to –50 dBm, 0.1 to +30 dBm)
≤ ±
1.5 dB (–80 to –70 dBm)
