Test signal level monitor function
• Test signal voltage and test signal current can be monitored.
• Level monitor accuracy:

Test signal voltage 2 Test frequency Specification
5 mVrms to 2 Vrms ≤ 1 MHz ±(3% of reading value + 0.5 mVrms)
> 1MHz ±(6% of reading value + 1 mVrms)
> 2 Vrms ≤ 300 kHz ±(3% of reading value + 5 mVrms)
> 300 kHz ±(6% of reading value + 10 mVrms) 3

1. When auto level control function is on.
2. This is not an output value but a displayed test signal level
3. Typ. when test frequency is > 1 MHz with test signal voltage > 10 Vrms.
