Test Signal

Frequency

75 kHz to 30 MHz, 100 Hz solution

Frequency accuracy

±0.01%

Signal modes

Normal – Program selected voltage or current at the measurement terminals when they

are opened or shorted, respectively

Constant – Maintains selected voltage or current at the device under test (DUT)

independent of changes in the device’s impedance.

Signal level

The following test signal level accuracy is speciﬁed for an ambient temperature range of

23 °C ± 5 °C and the test cable length is 0 m.

For the temperature range of 0 °C to 55 °C, multiply the temperature induced setting

error listed in Figure 1-5 to the test signal setting accuracy. When test cable length is

1 m or 2 m, add the following error due to test cable length.

0.2 x f_mx L [%]

where:

f_m= Test frequency [MHz]

= Test cable length [m]

Output impedance

The following output impedance is speciﬁed for the test cable length of 0 m:

(25 + 0.5 f ) Ω ± 10 + f_m
