Test signal level monitor

The following test signal level monitor accuracy is speciﬁed for an ambient temperature

range of 23 °C ± 5 °C and the test cable length is 0 m.

For the temperature range of 0 °C to 55 °C, multiply the temperature induced setting error

listed in Figure 1-5. When test cable length is 1 m or 2 m, add the following error due to

test cable length.

S_mon0.2 x f_mx L [V]

where:

f_m= Test frequency [MHz]

= Test cable length [m]

S_mon= Readout value of test signal level

S_set= Setting value of test signal level

For example,

Test frequency:

Test signal level:

Monitor readout value: 500 mV_rms

Cable length: 1 m

Ambient temperature: 25 °C
