7. At expected input level ≤ −37 dBm, pre-amp is switched on.
8. Total absolute amplitude accuracy is the total of all amplitude measurement errors. This specification includes the sum of the following individual specifica-
tions: linearity, expected input level switching uncertainty, IF bandwidth filter switching uncertainty, absolute amplitude accuracy. The wide range of settings
used (i.e., expected input level, etc.) are tested independently. The individual error contributions are calculated as follows: a 99.8 % proportion and 95%
confidence are computed for each parameter on a statistically significant number of instruments. The root-sum-square (RSS) of these four independent
Gaussian parameters is then taken. To that RSS value, two environmental effects and measurement uncertainty are added. One environmental effect is that
of temperature (full and controlled temperature range, as defined above) and the other is the temperature variation of ±3 degrees around a field alignment.
Applies over the following subset of settings and conditions: expected input level −50 dBm to +30 dBm; input signals within 60 dB below expected input level;
40 MHz and 160 MHz IF filters; input signal at center frequency over full frequency range.
9. The absolute amplitude accuracy is the amplitude measurement error when only changing frequency. The expected input level, conversion type
and IF bandwidth settings remain the same and the error introduced by those parameters are not included. Pre-amp auto/OFF expected input
level +10 dBm and −12 dBm. Pre-amp ON expected input level −30 dBm.
10. Typical specifications shown at M9350A downconverter reported module temperature of 46 ºC and a corresponding environment temperature
of 25 ºC.
11. When using pre-amp auto mode, applies for signal level within expected input level >−37 dBm.
12. When using pre-amp auto mode, applies for signal level within expected input level ≤−37 dBm.
