The QOAL400
module is a precision instrument capable of
measuring all common parameters of an Op Amp,
including AC as well as DC parameters.
The QOAL400 has four
completely independent channels, which allow a
quad device to be tested in a minimum amount of
time. Each channel has a full set of resources to
measure all common parameters. Parameters such as
Av, Vos, Ib, Ios, GBW, Slew Rate, Rise Time,
Supply Current, PSRR, CMRR, Vout, Iout, etc. may
all be measured with this card. This is the only
card necessary for the MTS-2010 to fully test a
quad Op Amp IC.
The QOAL400 uses an onboard
controller, which relieves the system CPU of
performing many functions necessary for the
module operation. The result is higher efficiency
of the CPU and faster execution of the module
commands. All measurements use the “Zero
Time Average” (ZTA) circuit (patent pending)
that allows for a measurement time of less then
250 us to the full 16-bit resolution. ZTA enables
the QOAL400 to obtain the repeatability of using
20 to 50 measurements and averaging the results,
with a single measurement.
