a. Performance Check
(2) Allow equipment to warm-up for 1 hour before proceeding to (3) below.
and RF output level to +5 dBm.
(4) Establish a reference on receiver system at test frequency.
(5) Press receiver system MEAS-REF pushbutton.
(6) Disconnect short from equipment setup (fig. 1). Record receiver system readout
indication (to include the sign).
(7) Connect TI to VSWR bridge and record receiver system indication.
