TEKTRONIX AFG31252 任意波函数发生器 (250 MHz, 2 Channel, 2 Gsa/s)

Amplitude

Range (into 50 Ω) ≤ 200 MHz: 1 mVP-P to 5 VP-P

> 200 MHz to ≤ 250 MHz: 1 mVP-P to 4 VP-P

Output impedance 50 Ω

Load impedance setting Selectable: 50 Ω, 1 Ω to 10.0 kΩ, High Z (Adjusts displayed amplitude according to selected load impedance)

Isolation 42 Vpk maximum to earth ground

Short-circuit protection Signal outputs are robust against permanent shorts against floating ground

Overcurrent protection When incoming current is greater than 250 mA, the output channels are protected with relays that disconnect 

the AFG from the device under test. Connection can be resumed by user after removing the incoming current
