AP-1M Hi-Z Adapter
The AP-1M adapter provides a means to connect a high-impedance input to your instrument. In
order to achieve high bandwidth with excellent signal integrity, these instruments have a +/-4 V
dynamic range and 50 termination to ground. However, for applications that combine one or more
high-speed signals with slower, higher-voltage signals, the AP-1M provides a 1 M input impedance
path and a full-scale range of +/-8 V. It is also suitable as an interface for current probes that require
a 1 M input path.
In addition to acting as a ProLink-to-ProBus adapter, the AP-1M also enables a much larger offset
voltage range (up to +/-50 V).
The AP-1M is supplied with a PP005A passive probe.
Auxiliary Output Signals
In addition to a calibration signal, the following signals can be output through the AUX OUTPUT
connector:
Square Wave
Trigger Out -- can be used to trigger another scope
DC level -- a reference level
