[a] "–" signifies that the LO frequency times the LO harmonic number is higher than the RF input frequency. LO × N = RF + IF.
[b] Harmonic number is dependent on the start and stop frequencies. Harmonic –6 is used from 60 GHz to 78 GHz and harmonic –8 is used
above 77.5 GHz.
[c] Exact LO frequency is dependent on the IF path setting of the signal analyzer.
[d] Conversion loss values shown include the effect of an internal IF amplifier.
[e] Calibration accuracy is the difference between the conversion loss factors measured and programmed into the M1970 at the factory and the
actual conversion loss of the mixer experienced when used with an X-Series signal analyzer with option EXM. The values shown include test
system uncertainty, interpolation error, and the effects of the difference between the X-Series environment and the factory calibration
environment. The system amplitude accuracy is worse than this M1970-only calibration accuracy due to SWR effects between the M1970 and
the X-Series IF input, and due to Gain Accuracy at the IF Input in Option EXM of the X-Series analyzer used.
[f] The values shown are the noise figures of the M1970 alone. They include effects of the internal IF amplifier. The system noise figure when
connected to an X-Series signal analyzer will be higher, by nominally 0.8 dB.
[g] System DANL includes the effect of an X-Series analyzer and cable as well as the M1970. DANL is defined with log-scale averaging according
to industry conventions. The noise density is about 2.25 dB higher than DANL.
