Atec Agilent-E4432A-1E5 - Manual (Page 3)

Input Voltage RF Off: -1.0 V RF On: 0 V Linear Control Range: 0 to -1.0 V Internal Modulation Source Provides FM,
PM, and AM Modulation Signals and LF Out
Waveforms: sine, square, ramp, triangle, pulse, noise
Rate Range Sine: 0.1 Hz to 50 kHz Square, Ramp, Triangle Optional I/Q Baseband Generator (Option UN3 or UN4)
Supported Standards: DECT, GSM, NADC, PDC, PHS,and TETRA
Data Structure Frames and timeslots may be configured as different types of traffic or control channels. The data field
of a timeslot can accept a user file, PRBS (PN9 or PN15), or external data with the appropriate clock.
Internal Data: Pseudorandom Patterns (meets ITU-T standard): Continuous PN9 (PRBS 2
9 -1) or PN15 7 (PRBS 2 15 -1)
Repeating Sequence: any 4-bit sequence
Downloadable Data (User Files): Type: Serial Data Minimum Size: Must fill entire field for which it was selected
Maximum Size: 1 Mbits (Opt UN3), 8 Mbits (Opt UN4)
External Data: Type: Serial Data Inputs: Data, Bit/Symbol Clocks Accepts data rates ±5% of specified data rate
Reference Frequency Internal or External: 1, 2, 5, 10 MHz reference Data clock can be locked to the external 13 MHz
reference (GSM)
Frame Trigger Delay Control Range: 0 to 65,000 bits Resolution: 1 bit
Internal Burst Shape Control Rise/Fall Time Range: up to 30 bits Rise/Fall Delay Range: 0 to 63.5 bits (varies with
standard)
7 PN15 is not continuous in bursted mode for TETRA applications. NADC (Option UN3 or UN4)

Data Rate (default): 48.6 kbits/sec Adjustment Range: 40 to 75.5 kbits/sec
Filter: Root-Raised Cosine or Raised Cosine Default Value: alpha = 0.35 Range (alpha): 0.3, 0.35, 0.4, 0.5, 0.6
Error Vector Magnitude (%rms)
8
[see table 1]
Channel Spacing: 30 kHz
Adjacent Channel Power 8 (ACP)
(Low ACP Mode, dBc, typical)
[see table 2]
Supported Burst Types: Custom, Up/Down TCH
8 Specifications apply for the frequency range, data rates and filter factors
(alpha) specified at power levels >=+7 dBm.
9 The "channel spacing" determines the offset size of the adjacent and alternate
channels: Adjacent Channel Offset = 1 x channel spacing, 1st Alternate Channel =
2 x channel spacing, 2nd Alternate Channel = 3 x channel spacing, 3rd Alternate
Channel = 4 x channel spacing.

10 Specifications apply for the frequency range, data rates and filter factors
(alpha) specifiedat power levels >=+7 dBm.
