X-Y
The HP 8340A is equipped with outputs to control
currently existing HP X-Y analog recorders, which
are listed below in Table 1. The 8340A must be
placed in the
with an X-Y recorder. Various control lines must
also be interconnected;
below and a typical setup is also shown in Figure 1.
X-lnput: The X-input to the recorder is generqlly
the SWEEP OUTPUT of the 8340A, which is sup­
plied by a BNC connector on both the front and
rear panel of the 8340A.
Y-lnput: The source of the Y-axis voltage to the
recorder depends on the equipment being used in
the measurement setup. If the 8755S Frequency
Response Test Set is being used, the Y-input
would be AUX A for channel 1 and AUX B for
channel 2. For 8410B/C systems, the 8412A/B dis­
play provides amplitude and phase outputs to the

recorder Y-input via the AMPTD and PHASE BNC
connectors, respectively. If the HP 436A Power
Meter is used, its RECORDER OUTPUT BNC con­
nector should be used.
Care should be taken to allow the recorder
enough time to respond to fine-grain variations in
the Y-axis voltage. Recommended 8340A sweep
times for each X-Y recorder are given in Table 1.
Pen Lift: The PEN LI FT control line is assigned to
a pin on the remote control connector of the
recorder, as shown in Table 1. (For a complete list­
ing of all pin assignments on the remote control
connector, refer to the Operating and Service
Manual of the recorder being used.) The PEN LI FT
control line is connected to the PEN LIFT OUTPUT
BNC connector on the rear panel of the 8340A.
PEN LI FT OUTPUT is operable only if the 8340A
sweep time has been set to a value greater than
5 sec.
