HP 3336A Operating Manual page 36

The Z BLANK Output low level is capable of sinking current from a positive voltage source
through a pen-lift relay or other device. The Z BLANK Output ratings are:
Maximum Current.......... 0.0.0 cc ccc ee cee cee eens 200 mA
Voltage Range. .... 0... 0... ccc cc cee eee 0Vto +45 Vdc
Maximum Power (output voltage x current).............. 1 Watt
3-85. AMPLITUDE MODULATION.
3-86. Amplitude Modulation Selection.
3-87. To program Amplitude Modulation, press the BLUE shift key followed by the AM
ON (STORE) key. To disable Amplitude Modulation, press the BLUE shift key followed by
the AM OFF (RECALL) key. The AMPTD MOD annunciator will light when Amplitude
Modulation is enabled.
3-88. When Amplitude Modulation is enabled and no modulating signal is present, the out-
put level is the programmed level. At 100% modulation, the maximum output amplitude
will be twice the programmed level.
3-89. Amptd Mod Input. (Located on the rear panel) is the modulating signal input. This
input is rated: .
Maximum Input Voltage................-22 eee eee +5 V peak
Nominal Input Impedance............ 20 k ohm, 10 k ohm when
Amplitude Modulation is OFF
Input Sensitivity.............. = 10 Vp-p for 100% modulation
Frequency Range.......... 0... cee eee eee eee 50 Hz to $0 kHz
Envelope Distortion............... — 30 dB to 80% modulation
3-90. PHASE MODULATION.
3-91. Phase Modulation Selection.
3-92. To program Phase Modulation press the BLUE shift key followed by the PM ON
(CLEAR) key. The Phase Mod annunciator will light when Phase Modulation is enabled.
To disable Phase Modulation, press the BLUE shift key followed by the PM OFF (—) key.
3-93. Phase Mod Input. The PHASE MOD Input (located on the rear panel) is the Phase
Modulating Signal input. This input is rated:
Maximum Input Voltage............... eee eee eee +5 V peak
Nominal Input Impedance................ 0.00 eee 10k ohm
Input Frequency Range.......... cece eee ee ees dc to 5 kHz
Maximum @ Shift......... 0... cee cece eee eee een eee + 850°
Input Sensitivity 342. ois a Ape Sas eee Sees = + 170°/volt
3-94. OPERATING STATE STORAGE.
3-95. Up to ten entire instrument operating states (programs) may be saved for use in the
future. Each instrument state is stored in a location identified by a number from 0 to 9. To
