Model selection tip:
Choose the model that covers your highest intended test frequency with ~20–30% headroom.
3135C → up to 100 kHz,
3138C → up to 200 kHz,
3139C → up to 300 kHz.
Typical guide: general capacitors/inductors ≤100 kHz → 3135C; RF/EMI parts up to 200 kHz → 3138C; wide-band characterization or fixtures above 200 kHz → 3139C.
