校准精度，是保证向两端惠普41941 a (1.5 m)和惠普41941 b(3米)阻抗探头。
Calibration accuracy is guaranteed to the tips of the HP 41941a (1.5 m) and HP 41941b (3 m) impedance probes.
X1探头﹕没有衰减﹐输入阻抗跟示波器输入阻抗一样(通常是1兆欧)。由于对测试电路有很大的负载影响﹐所以很少使用这种探头。
X1 probe: no attenuation, input impedance follow that of scope input impedance (usually 1 Mohm). This type of probe is seldom used because of heavy loading effect on circuit under test.
