VXi VT1529A/B 사용자 설명서

where R is the completion resistor value in k

Ω.

With V

excitation

 = 5.000 V, the nominal output voltages can be computed:

for R = 0 

Ω,     Vsense = 0.357143 V

for R = 120 

Ω, Vsense = 0.337684 V

for R = 350 

Ω, Vsense = 0.301120 V

Note that the actual measurements will vary based on the actual resistor 
values in the dummy load, so these values should be considered approximate 
when running this test.

The VT1529A/B must be connected to the VT1422A through the VT1539A 
SCP. The Dummy Load must be connected to the channel(s) being tested.

The Voltage Source must be connected to the appropriate channel bank 
terminals of the Bridge Excitation input on the VT1529A/B.

The signal path through the VT1529A/B is highlighted in Figure C-3.

If necessary, send the *CAL? query to the VT1422A (required if more than 
eight hours has elapsed since the last *CAL? command). The expected 
return value is “+0”.

Set the Voltage Source to 5.000 V.

Configure the VT1529A/B for bending half-bridge operation using the 
SENS:FUNC:STR:HBEN (@<ch_list>) command. This switches in the 0

Ω
