Generally, frequencies between 1kHz and 10kHz are suitable for measuring inductances. The instrument is able to measure inductors from 10 uH with acceptable precision and from 100 uH with high precision.
Low inductances (< 10 uH) can be measured at 1MHz with accuracy about 5%. It is possible to measure inductance from about 100 nH.
Generally, range from 100Hz to 100kHz is usable for measuring capacitances. Higher frequencies are problematic as spears starts to act as an antenna and measurement of small capacitances is more difficult. At higher frequencies, parasitic inductances are more significant and influence the measurement.
For most common range capacitance values between 1 mF and 1 nF is suitable frequency of 1kHz. For measuring lower capacitances it is possible to use 10 kHz. At this frequency the instrument is able to measure capacitances bellow 1pF. Capacitances over 1mF require usage lower frequency (100Hz).
Measuring impedance curves
Thanks to widely tunable DDS (1Hz to 1MHz) the instrument is able to measure impedance in wide range of frequencies. One possible application of this is to scan impedance characteristic of audio filters.
Measuring frequency and period
Without divider, it is possible to measure frequency upto 300 MHz on both channels, with timebase 1s or 10s. Inputs could be in AC or DC coupling mode. For low frequencies and higher periods ( < 10 Hz or > 100 ms) it is suitable to use DC coupling.
