6. Set the signal generator frequency to 2785 MHz.
7. Set the signal generator amplitude to –23 dBm.
8. Set the tunable band pass filter (K&L 5BT-1500/3000-5-N/N) near 2785 MHz. A lternatively, a 3300 MHz lowpass filter,
K&L 5L250-330
0/E 10000 -O/OP, may be used i nstead of the tunable filter.
9. Adjust the tun
able filter for maximum power on the power meter.
10. Set the signa
l generator output to –30 dBm at the power meter. This is also the amplitude at the input of the RSA306B.
The generator amplitude will be close to –23 dBm.
11. Measure and record the 2RF X 2LO spur amplitude for these settings. (See Table 23 on page 52.)
12. Calculate and record the 2RF X 2LO spur amplitude in dBc (2RF X 2LO spur amplitude (dBm + 30).
13. Set the signal generator output to Off.
14. Disconnect the tunable band pass filter and install the 5000 MHz cutoff, L250 low pass filter in its place (K&L
5L250-5000/E 15000– O/OP).
15. Set the signal generator output to On.
16. Set the RSA306B to 2870 MHz center frequency.
17. Set the signal generator frequency to 4655 MHz.
18. Set the signal generator output to –30 dBm at the power meter. This is also the amplitude at the input of the RSA306B.
The gener
ator amplitude will be close to –23 dBm.
19. Measure
and record the 2RF X 2LO spur amplitude for these settings. (See Table 23 on page 52.)
20. Calcula
te and record the 2RF X 2LO spur amplitude in dBc (2RF X 2LO spur amplitude (dBm + 30).
21. Record r
esults in the Test record.
NOTE. This table includes the worst 2RF X 2LO spurs observed on the RSA306B.
